Knitting at Nine Worlds

At Nine Worlds Geek Fest I delivered a session which was basically about making yarn from bought clothes. There are two main ways of doing this which I covered in my session – unravelling bought knitwear, and making yarn from jersey fabric (usually t-shirts).
I wrote this blog post so that people who didn’t make it to the session can find out what they missed ūüôā


T-shirt yarn

This is made from jersey fabric, usually in the form of t-shirts. You can use old t-shirts, t-shirts you never wear, t-shirts bought from thrift shops/charity shops (especially those who sell clothing by weight) or if you have a particular yarn result in mind you can make it out of brand new t-shirts. If you are buying t-shirts to make yarn out of, try to get the biggest size possible. The yarn is made from the section of the shirt below the armpits so the longer the shirt, the better.

Once you have got your t-shirt, you next need some sharp scissors Рdressmakers scissors are ideal. You can also use a rotary cutter if you prefer. Cut a horizontal line across the shirt, right under where the arms join to the body. You may find it helpful to draw a line onto the fabric first with a ruler, to make sure that it is straight. You can buy special fabric pens to do this, or dressmakers chalk which is cheaper, or you can use the corner of a bar of soap.

Now you should have a rectangular tube of fabric. Your next aim is to make a spiral cut so that this is turned into one long thin strip of fabric. There are a couple of ways of going about this. The first way is to start at the bottom edge, cutting in a slope into the fabric until the strip you are cutting is about 2cm wide. Any thinner and you will have problems at the next stage. Then just carry on cutting, keeping your cut the same distance away from the edge of the fabric. Hopefully you will end up going round and round until you’ve got to the top. The second way of cutting the fabric is to lay it out flat and make a series of parallel cuts into the fabric – do not cut all the way across or you will have lots of loops instead of a single strip! This is another point at which you can draw the lines on if you prefer. Cut until about 5cm away from the edge of the tube. You will then have a vertical strip of fabric with lots of loops hanging off it. Then you go along this solid edge, joining up each cut with the next one up. This joins all of the loops into a single strip.

Now that you have a single strip of fabric the next step is to stretch it. I usually do this at the same time as winding it into a ball but you can do these two steps separately if you prefer. All you need to do is go along the length of the strip, stretching it reasonably firmly between your hands. This causes the edges to roll up and the strip to look more like a piece of yarn. Once you’ve got it all wound up into a ball it is ready to be made into something.

The yarn can be knitted, crochet, woven (although it is stretchy so you need to bear this in mind), or used to make things like rag rugs or proggy mats.

Unravelling knitted items.

This can be a very cheap way of getting hold of yarn. At the moment high street shops have a lot of knitwear in them, and in the sales you can pick up jumpers for as little as 3 GBP. Often the ones in the sales are the extremes of size, and since you will be unravelling it, getting as big a jumper as possible is to your advantage.

The first step is to identify which jumpers are suitable for unravelling. Some mass produced knitwear is made by knitting a large sheet of fabric, then using an overlocker to sew it together, which sews and cuts the fabric at the same time. If you are wearing a t-shirt, then the seams will probably have been done with an overlocker.

This is no good for unravelling, as instead of having a jumper knitted with a few lengths of yarn, you have a jumper where the yarn has been cut into lengths as wide as the jumper is. Unless you are happy having lots and lots of bits of yarn a metre or less in length, these are not thje jumpers you are looking for. The jumpers you are after are ones in which the pieces of the jumper (ie front, back, sleeves) have been made separately and then sewn together. [pictures of the right and wrong kind of seam]

The second step is to figure out if the yarn will be any good once the jumper has been unravelled. Mass produced knitwear often uses yarn which is made of many thin threads held together, whereas yarn sold for knitting usually has one, two or three strands twisted together, which makes the yarn more robust and much easier to use for hand knitting. A bought jumper made of strands held together is not necessarily useless for unravelling – you will need to pay attention when knitting it to make sure the yarn is not splitting as you are knitting it. This can be an advantage however as it means that you can hold strands of the unravelled yarn together to make a thicker yarn, without it looking odd. [picture and explanation of unicorn hat and strands]

Another factor which can effect the result you get is whether the jumper is made with a single yarn or using different colours of yarn. Obviously using different yarns means that the length of each yarn will be shorter than if the jumper were made with just one colour. Fairisle jumpers are much more difficult to unravel as the strands are often twisted around each other. I would not attempt to unravel a fairisle patterned jumper as I think it would be far too much effort, but if you’ve got the time and patience to do it then there is no reason not to try.

The third factor which you need to take into account is¬†the fibre/yarn type. Mohair and other fluffy yarns tend to¬†be more difficult to unravel.¬†With a mohair jumper you cannot just grab¬†the yarn and pull it to unravel, you have to unravel it stitch by stitch and it often gets tangled. If you are buying a second hand¬†jumper which is made of yarn with a high wool content, then it may have slightly felted together in places, which will make unravelling more difficult. If you¬†are unravelling a jumper and are finding that it is resistant to unravelling, there are a couple of things that you can do. One is to¬†soak it in water with fabric¬†softener or hair conditioner in it – this lubricates the yarn a bit, hopefully¬†helping it to slip past itself¬†and unravel more smoothly. Another is to put the (dry) jumper into the¬†freezer. I’m not sure how this one works but¬†I’ve heard that it does help!

Once you have identified that the jumper is of suitable construction and the yarn is likely to be usable, the next step is to get it¬†home and start unpicking the seams.¬†Your best friend in this step is a stitch ripper [picture] which you can get from a craft shop/haberdashery department for a couple of quid. I usually unpick the side seams first,¬†and then the sleeves and shoulder seams, which¬†should break the jumper down into its component¬†parts. Often the sewing technique used on the seams is such that¬†if you pull on the right¬†bit, it falls to pieces in your hands, which is most satisfying! If you can’t find the magic thread, then you will have to unpick it¬†stitch by stitch. I usually hold the seam with the right side of the fabric facing me, with one side in each hand [picture], and pull the two¬†sides apart¬†so that I can see the joining thread in the gap between the yarn. An alternative is to unpick from the wrong side [pic]

The¬†trickiest bits are usually the labels and the armpits. Labels are sewn onto the fabric¬†and can usually¬†be unpicked but you may have to give in and cut it out. Armpits are tricky just because there’s usually two different seams coming up against each other and so¬†figuring out which thread is holding you back can be more difficult.

Once you have the jumper¬†deconstructed into flat pieces, you can start unravelling the yarn. Knitting unravels in the reverse of the direction that it was made,¬†and most commercially made jumpers are knitted from the bottom up, so you¬†need to¬†try to find the end at the top of the piece. If however you are struggling away¬†trying to unravel a¬†piece from the top, it is worth trying to find the end at the bottom just in case it was made the other way around. The ends of the yarn are usually sewn in to¬†one of the edges of the fabric. Once you have found it, you¬†will need to undo (or cut) the last stitch that was¬†knitted, and¬†from there you should be able to pull the yarn, causing the row to unravel. After the first stitch, you should not need to thread the yarn through¬†anywhere –¬†I’ve found that trying to do so can cause more problems than it causes so¬†do so with caution. It *should* just unravel. It is¬†worth winding¬†the yarn into a ball as you go along, as tempting as it might be to¬†just keep pulling¬†on the¬†yarn until the¬†whole piece has disintegrated. If you don’t wind as you¬†go, you will have¬†turned a¬†flat piece of¬†fabric into a tangled pile of yarn which you¬†then need to untangle, instead of a neat ball of¬†yarn.

You can either use the yarn it as-is, or you can wind it into skeins to get the kinks out. I use a niddy noddy which you can buy (or make out of PVC pipe reasonably easily) or you can wind it around an object like a cardboad box. Once it is in a skein, tie some threads around it to stop it getting tangled, and then either hang it up in your bathroom to let the humidity get the kinks out, or soak it in water and then hang it up to dry. You will then need to wind it back into a ball Рdo not be tempted to knit from the skein, it is way more hassle than winding it into balls!

Next year I’m considering¬†doing another session on¬†making¬†yarn¬†out of stuff you’ve bought, but this time moving away from fabric/yarn and¬†towards¬†things like plastic bags, straws, wire etc.

Do you¬†recycle clothing into yarn? Do you have any projects or techniques you would like¬†to share? Or do you have questions¬†or comments about what I’ve written here? If so please post a comment below – I would love to hear from you.

  1. Good post , thankyou! I have never tried making t shirt yarn but I would like to try some cheerful rugs ūüôā I have done quite a bit of unravelling though and I would add that when choosing something to unravel another factor is how I thin the yarn is – you had best make sure that cobweb weight came blend is really worth it s it will cost you a lot of time and effort! I have usually found thin weights of pure lambswool are basically un-unravelable. I would also add that unravelling is a great opportunity to delve into relatively inexpensive food dye experiments, and you can use the sleeves as ready made dye blanks ūüôā

    • Oooh great idea with the dye blanks! As long as you get yarn that will take dye (100% synthetic probably won’t)
      Yes the yarns they use often seem to be more fragile than commercially available knitting yarns, I’m not quite sure why.
