Yup, it stretched better when I moved it to the wider part of the board. There is a metal brace under that part but it didn't matter.
Here are my results. The demin patches I bought (carefully chose the light blue denim so they would match) would not stick for love or money. Do not buy Wright's denim knee patches. Wright's is lovely for bias tape, but not patches. I followed the directions, preheated the area, put the patch sticky side down, ironed them with a dry iron on 'Cotton', they were not stuck. Ironed them again and again. Finally the patch itself was beginning to scorch and it still was not stuck, so I gave up.
I remembered I had the white patches that I bought for her quilted playpen cover, and they worked beautifully. I've washed it a lot and she's bounced around in it a lot and it has staying nicely mended because THOSE patches stuck. So I got out the white Dritz patches and tried those. I did not want white, it doesn't match, but the diapers are going to have to be thrown away soon otherwise.
Anyway, the white patches stuck. They are a thin fabric but there is so much adhesive that I have a feeling they will hold together a while longer. ALSO, there was an unintended consequence of all that pressing with a hot iron--the elastic in the leg holes in the crotch area apparently melted so they no longer stretch or pucker. But I put one on her this morning and I don't think it's going to matter. Now that the diaper is not puckered in the crotch, I could probably sew a good denim patch on rather easily and have it match. Or maybe even a colored patch.

So...we will try them like this for a while and see how it goes. I only got 4 done because I ran out of the white patching material.
PS. Bobbie I just ordered a Pooch Pad diaper to try off eBay. I don't know if it will be absorbent enough but it will work with a pad if it is not. The pad also gives her padding to bounce on, like the Charmin kid!

Thanks!
