This is part of my research for my MA in Design. I’m exploring the idea of infinity.
I’ve made a few of these now, mostly using scrap yarn and they are a brilliant way of using up odd ends. They work better with stripes so you can see the never ending edge.
They are quite a mindful thing to play with. Without exception, everyone I have handed one to has been surprised and delighted. At the end of the project I’ll donate them to a dementia cafe so if you know of one in Bristol please let me know – links to my social media are at the bottom of this post.
If you use Ravelry I have a link to the pattern there too. If you don’t use Ravelry, or have never heard of it and like knitting or crochet beware the rabbit warren! I can lose days looking at patterns on there.
Mobius strips are just a strip of paper/cloth/crochet with one twist in them but that one twist does amazing things. When you join the ends together the strip has just one side and one edge. This means if you are making a mobius strip in crochet you can just keep going around and around and making it bigger.
The hyperbolic aspect is formed by the increases. You can play around with these and have more to make a frillier edge or less to have it tighter. In there is a table of increases that will help you get a perfect line. I’m just doodling with these and they don’t need to be perfect. Crocheting Adventures with the Hyperbolic Plane is a great book if you want a deeper delve.
Make the mobius strip
If you are new to crochet you will only need to know 2 things, the first is how to make a chain and there is a good YouTube tutorial here.
For this hyperbolic mobius toy I used Super Chunky yarn and a size 8mm hook. I’ve made them in DK with a 4mm hook too, your stitches need to be quite dense so you don’t get a floppy toy.
The annoying thing about crochet is that there are different terms in the UK and in America. I’ve called the stitch I use Single Crochet, which is actually the American term, in the UK we call it Double Crochet. For simplicity, and because I found a tutorial calling it single crochet I’ll stick to that. It doesn’t really matter what stitch you use though and it might be fun to try different ones as you go along.
If you need a tutorial for single crochet try this one.
Join the ends
You need to twist the ends of the crochet strip so the top joins the bottom now.
Start the hyperbolic increases
When to stop
Because this is an infinite line you can go on forever in theory, in practice you will either run out of yarn or the centre hole will get full. You can join yarn together by knotting it and sewing in the ends when you are finished.
I’ll make a detailed video as soon as I can but if you make one of these, please let me know how you get on. I’ll add more crochet, knitting and sewing tutorials to the site in the near future.
