Storing your knitted swatches

I always have trouble with swatches.  Not in the act of making them – swatching can actually be kind of fun – but in the storing process.  Specifically, how to store them with the appropriate information attached so that you can access it again.   Normally, I will knit one or two or three swatches with a particular yarn, using different sized needles.  I will then wash and block and carefully measure the swatches.  They will then get thrown in a plastic bag and put in a basket for a while.  Some time later, I will find the swatch but not know what size needle I used, and just to be sure, I would knit the swatch all over again.

I have tried to be clever and write it down in a way that I can access the information many months, or years, later.  Storing notes on Ravelry would be useful, but it still doesn’t let you feel the swatch and decide which fabric gauge is most suitable for the project you are thinking about.  Of course, normally I just scribble it on a piece of paper and the information is lost to posterity and when I find a swatch I want to replicate into a garment I don’t know the needle used, and often don’t know what yarn it was knit in either.

I tried attaching the labels to the swatch, by pinning them for example, but this never worked.  Put enough swatches into a bag and they end up all jumbled up and the labels get detached.  I read somewhere about using yarn overs in the swatch to indicate the needle size – 3 yarn overs, which create 3 holes across one row of the swatch, would indicate a size 3 needle.  Well, this caused problems for me because I live in a cross-over world where I equally use US needle sizes and European sizes (in mm), and also because what do you do with half sizes?

Recently, I decided to try something new.  I knit the swatch, wash and block it, and then store it in a plastic file folder that hooks into a ring binder, along with all of the relevant information – yarn, needle size, stitch used, etc.  Here is an example:


This is a swatch knit with Carol Feller’s yarn, Nua.  In the pocket is the actual swatch along with a piece of paper with the relevant information written on it.  In this case, it tells me that the swatch is knit in stockinette with a US 6 needle, that Nua comes in 50g/140m skeins and is composed of 60% wool, 20% linen, and 20% yak, that the colour used for the swatch is called Unexpected Macaw, and that the blocked gauge is 22×34.

Here are two swatches that I made for my Form pullover:


This pullover was knit with two strands of yarn held together.  I knit two swatches with two different needles.  I have created a separate page for each needle size, so that the two swatches are easily identified without having to take out a measuring tape to see which is which.  The information on the page identifies both of the yarns used.

Here is another example, in which I have included both the stockinette gauge and the ribbing gauge for the 4ply Hampshire yarn from The Little Grey Sheep:


I use a very heavy-duty clear pocket folder made by Leitz.  I have a couple of boxes of them left over from my years in Germany.  This method won’t work with the typical floppy lightweight folders; you must have access to the heavyweight type.  I imagine you can find them in a good stationary or office supply shop.

What I like about this method is that the swatches can then be stored in a binder on a bookshelf, all the information is contained in a readily accessible way, and the swatches themselves can be large enough to be be useful.  I have only been using this method for the past few months.  We will see whether it turns out to be practical over the long run and also whether I will actually stick with it (I am notoriously unorganised).

Do you struggle with keeping track of your swatches?  Have you developed any good tricks?

The joke’s on me

Yesterday, I thought that I would do some swatching for my new sweater.   I am going to knit the lovely pattern, Exeter, designed by Michele Wang:

I am going to use the same yarn and colour as in the pattern, Shelter by Brooklyn Tweed in Fossil.   You can probably tell by the title of the post that there is a joke (of sorts) involved here.  First, I will explain what a swatch is and why you need it, then I will provide a set-up and the punchline.

Part 1: The swatch

Now, we all know that in order to get a sweater that fits, you have to have the right gauge.  The sweater is designed to a particular gauge – that is, it is designed so that x number of stitches and x number of rows measure out to a given size.  Traditionally gauges are given for a square measuring 4″ (10cm).  Exeter is designed for a gauge of 20×28; this means that a 4″ square section of fabric will have 20 stitches across and 28 rows.  Normally a gauge will be given for stockinette stitch, but might be given in a pattern stitch.  Gauge is nearly always determined based on a washed and blocked sample.

Since different knitters knit with different tensions, the only way to make sure your sweater fits as the designer intended is to knit up a sample (called a swatch) on a particular size knitting needle, then wash and block it, let it dry and measure it carefully.  If your gauge is too narrow (ie, more stitches or rows than called for) then you must knit another swatch with a larger size needle (ie, a needle with a bigger width).  If your gauge is too wide (ie, less stitches or rows than called for) than you must try again with a smaller sized needle.  Each of these measurements must be taken on a swatch that has been washed and blocked and dried.

An experienced knitter will be able to adjust a pattern even if their gauge is not quite right.  Also, sometimes, you might hit the stitch gauge but not the row gauge (this happens to me all the time).  Then, you have to make a judgement as to which is the more important one to get right (which depends on the pattern) and make adjustments as you knit.  These kinds of manipulations are tricky, and take both experience and math skills.  Obviously, the best solution is to match the given gauge as carefully as possible; then, you can follow the directions as written.  (Note that you may still need to adjust the pattern – for example, the sleeves should fit you, and therefore you need to knit to your arm length.  However, hitting the right gauge will save you lots of headaches.)

Part 2: The set-up

Now we come to an interesting problem.  Sometimes, you need to knit quite a few swatches before you hit the right gauge.  Notice that the most important element of the swatch is to identify it with the needle size it was knit with. While the swatch is on your needle, it is easy to tell what needle size the swatch represents.  Once you take it off the needle, the problems begin.  Let’s say that you end up knitting 4 swatches, one each with a US size 4,5,6, and 7.  Now, you throw them all in the basin, soak them, blot them between towels, block them, let them air dry and then carefully measure.  And you’re in luck – one of them exactly matches the gauge!  Yes!  But which one was it?  Is this the swatch you knit with the size 5 needle?  Or, perhaps, you somehow mixed them up in the process….

I cannot tell you how many times I have knit a swatch and then come back to it and can’t remember what size needle I knit it on.  This is especially problematic if you come back to swatches weeks or months after they were made, or when you have multiple swatches of the same yarn.  I tried attaching notes to the samples with safety pins, but this solution isn’t the best either.  Notes get lost; they must be removed when washing.  Many times, I am forced to re-knit a swatch just to be absolutely certain.  (Of course, as with many things, keeping very careful notes is best; many knitters record all of their swatch measurements on Ravelry on their project page.  Unfortunately, I am often too caught up in the moment to do so; I am convinced I will remember everything and record it later, which is generally a bad idea.)

Now, when one is faced with a knitting dilemma, the answer can usually be found on Ravelry.  A few months ago, I was reading a thread in which a knitter was addressing this very problem.  She said that she had been taught a great tip by the knitting designer Ysolda Teague.  Ysolda told her to knit the needle size into the swatch.  Let’s say that you were knitting a swatch in stockinette stitch.  You knit a series of purl bumps into a corner of the swatch – one bump for each size. (Separate them out with a knit stich in between to make them easy to count.)  Thus, if you are swatching with a size 5 needle, you will knit 5 purl bumps into the right side of the fabric.  You will then know exactly what size needle you knit the swatch with, no matter how much time has gone by or how many swatches you’ve knit.  (Please note that you need to be consistent with units – either use US sizes or metric sizes consistently.  If using metric sizes, you can use a purl bump for each mm, and a yarn over for each 1/4 mm; thus, a 3.5mm needle would need three purl bumps followed by two yarn overs.)  Wow!  A system!  A pretty clever system at that!

I knit the first swatch for Exeter using a US size 7 needle.  I carefully (and very smugly) knit a series of seven purl bumps in one corner of the swatch.  Even before washing it, I could tell tell that I would need to try a larger needle, so I went to my box of needles to pull out a size 8 needle to knit the next swatch.  I was feeling very pleased with myself and my new system.  Never again would I be stuck not knowing which swatch was knit with which needle.

Part 3: The punch line

I use circular knitting needles almost exclusively.  Unlike straight needles, which usually have the needle size printed on the cap, for the majority of circular needles the only way to tell the size of the needle is to use a needle gauge.  A needle gauge is a tool which has labelled holes in it of different sizes. A size 6 needle will fit into the hole marked size 6, but will not fit into the hole marked size 5.  I am always losing my needle gauges.  They are never where I need them to be.  My solution is to have lots of them.  I try to  always keep one in the box with my circular needles, and one in the box with my DPNs, and one in my knitting notions kit, and one in each project bag.  I opened up the box with my circular needles, reached for the needle gauge and found a size 8 needle. I grabbed both the needle and the gauge and ran upstairs to knit.

I then started knitting my second swatch, very smugly knitting 8 purl bumps into a corner of the swatch.  Now for some unknown reason, I picked up the needle I had used to knit the size 7 swatch, and idly inserted it into the needle gauge I had just carried upstairs.  But, horror of horrors, it was not a size 7 needle but a size 6!  Oh no, I couldn’t have made such a basic mistake;  I was sure of it.  So, I tried the needle in the first needle gauge and it was a size 7.  No, this could not be!  The very same needle registered as a size 6 on one gauge and a size 7 on another!  I frantically ran around the house collecting needle gauges.  I found five (though I’m sure there are others scattered around):

IMG_6052The top two are ancient Susan Bates gauges with US measurements, the third one is a Boye gauge (also US), followed by a Tailorform gauge from Canada (with metric needle sizes and centimeters on one side, and US and Canadian knitting needle sizes and inches on the other), and the bottom one is a KnitPro gauge with both metric and US measurements.  The needle that I used for the swatch is the blue one in the right hand corner below:

IMG_6053This is an ancient needle, you can see that the blue enamel is wearing off.  I have no idea how old it is or which make it is.  However, this needle registers as a size 6 on the top three needle gauges and a size 7 on the bottom two.  Could it be that the US -produced needle gauges use slightly different measurements?  To check, I grabbed the needle on the top left of the photo.  This is a fairly new HiyaHiya interchangeable needle, which is still clearly stamped “US size 7, 4.5mm”.  I checked this needle against all of the gauges and it clearly registers as a 7 on all of the gauges.  So, perhaps this is a problem with the blue needle.  It is old, and possible worn.  I decided to check another new needle, the interchangeable KnitPro needle tip on the bottom left.  It registers as a size 6 on all of the gauges, except the Boye gauge, on which it is a size 5.  This divides the gauges along a different line than the blue needle.  Now, I start to pull my hair out.

Clearly, THE JOKE IS ON ME!  Here I am, smug as can be because I have found a fool-proof solution to figuring out which swatch was knit on which size needle.  But, it turns out, I have no idea which needle is which in the first place!  My seven purl bumps on the bottom of the swatch are rendered meaningless.

As an afterward: I poured this whole sorry tale out to Doug.  His solution: he went online and ordered me a micrometer, a precision instrument for measuring the diameter of a round object.  I throw myself on the mercy of the engineers.
