Lesson that I learned: ALWAYS try using your zipper BEFORE sewing! Also pay attention to what KIND of zipper you buy.. they are not all alike.
Well, it wouldn't have been that bad, use the seam ripper and redo it. However, I had made the project out of an old t-shirt that way if I messed up nothing would be lost... however... such an old t-shirt that the material ripped when I tried to undo it. When I tried sewing the zipper on the part that wasn't ripped, it was all crooked and totally not functional. So I have to start over with new material... I'll post when I actually complete the project right.
Good news is... I got to practice my applique and learned what NOT to do when sewing a zipper.
