Your roll up looks good, you did a great job. Maybe your having trouble because your pockets are all one size? When I made a roll up, I did different sized pockets leaving the larger ones to the outside end. Small tools roll easier and it gives the larger ones a little more room. That also helps with placing your ties or velcro (what ever you like best). You did do a really nice job. Remember, we learn new things every day. It's the same with sewing, how often have you changed a pattern after you have done it once. This is the same thing, sometimes the first it called a test pattern or a prototype - that's all this is.
