Most grocery baggers don't know what to do with the button holes on the handles, so I probably won't do those any more.
My shopping bags
I took apart a plastic shopping bag for the pattern size, and changed the handles to make it cheaper, but I've seen some that make handles part of the body of the bag. I change out handles too often on my other bags and wanted to be able to do that with these if necessary.
The road to success is always under construction.
