My June Ta Dah! Finished and now revealed.
If you read my post, I Know Something You Don't Know, you know I was busy for a week in June. I bought the cotton yarn (stylecraft cotton DK), set to with a will and a 3.5mm crochet hook and I made granny squares. 30 in total, 12 plain and the rest a lovely mix of red, yellow, orange, blue and ivory.
I joined the top squares with a line of single crochet on matching ivory, but I decided to sew the plain ones together so there was a contrast between the pattern and plain in texture as well as colour.
I used folded squares so that the bag could be long enough without being too long, but to make a shorter or longer bag would only be a matter of taking or adding a row or half row to the bag. It means the base is angled rather than squared, but I like that.
