If anyone has one please let me know I am trying to make my own with just a vinyl sheet I bought so if anyone can help me out with a diagram of it that would help. I am just having a problem with the button hole placements. Any in put would be great.

I know there cheap but I am trying to make a DIY so that anyone can make one from home for about 2 bucks and have it look almost or just as good as the ones that people pay 8-20 dollars for
