What I ended up doing, after many prototypes, was stacking the layers, stitching around the edge once with a wide zigzag, then trimming the uneven bits of cloth from the top view and again from the bottom view. Then I would go back and do a wide zigzag satin stitch all the way around, and another row that halfway overlapped, so they would hold up better in the wash. These are actually the ones that were reported to be more comfortable, too, which surprised me.
The ones I made for myself were all turned and topstitched so painstakingly! And sewing those snaps on by hand in those little pointy corners.....yikes! Yep, the final tinkle pads took a fraction of the time of the "nicer" pads......something like five to one. No, probably more like 10 to one!
Fear not, entrepreneurial stitchers!
