2 balls of yarn, 1 crochet hook and a good podcast…
I used 2 balls of Katía Jamaica in a yellow/green/red/brown blend and a 3mm hook.
Work 48 chain stitches, turn and work in slip stitches or double crochet – whatever you prefer – untill you have rectangle 20 cm wide and 53 cm long. Or thereabouts.
The fun part is the folding, inspired by Japanese furoshiki and bukuro. I’ll sketch some instructions for you. I just have to remind myself how I actually did it…
Stitch the bag together, and make a narrow strap (8 chains wide) and attach it to the top corners.
If you like you can leave your bag flat, or you can turn it inside out and fold the bottom corners to form a flat bottom and fasten the flaps with a few strong stitches.
You don’t have to crochet this – you could also use a felted, knitted rectangle or a length of fabric.
Make it small and use it as an evening purse or make it huge and use it for shopping.
