A shopping bag with plenty of room for all your yarn, and lots of leeway when knitting it up.

You can use 4-ply or DK, make the strap shorter or longer, or even change the size of the needles if you want to.

All you need is 100g of a good strong cotton, a pair of 4mm needles, a pair of 19mm (or 20mm) needles, and a bit of time. And you’ll have something that can go anywhere!
