Love making this bag, overall I find it easy to make. Although, there were some challenging parts for me - first, sewing the pocket; the rounded corners. It was more to do with me getting used to my machine, and controlling the turns when sewing. Second, sewing on the handles - it got quite bulky when I got to this part and I had no clips to hold them together, just pins. I used a snap fastener instead as it was a cheaper option for me, I am very new at sewing and did not want to spend too much for now. The bag folds up beautifully, and having the key strap makes it very handy - no more digging around looking for keys!
