I've called it the Crochet Club Bag, as I needed a new bigger bag to take to my weekly crochet group. Perfect for balls of yarn, and my makeup bag full of hooks!
It uses 800 grams of T shirt yarn (I used a cone from Lincraft) and a 20mm hook. It does also include a special stitch! If you'd like to improve your stitch repertoire, this will be a great way to do it!
The pattern is nearly written up, so check back in later this week.
