My trouble is the vinyl window...when I'm done stitching, it wants to come away from the hole...at the perferations that the needle has made. This is the second time now, that I've tried these I SPY BAGS, with the same results. Right now, the vinyl that I am using is from Walmart...red writting on the back...not sure what guage, but it's quite thick, but not the thickest they have. Does anyone have an idea what I'm doing wrong? I wanted to get one done for my little niece to take with her when she goes to pick up her new little sister in Colombia in a couple weeks...hhmmm...seems like it should work, just can't figure out what I could do to make it work!!
Hope to remember your tips if I ever try using plastic.
