Prism - Oof, really? It's all straight lines, I was just going to fold it over at the ends and when it got to turning corners. I have absolutely no idea what the ribbon will be like to work with, I ordered it from eBay and it hasn't arrived yet. The good thing is that I can fix this at any time, since the quilting is already done on this block, so I could even finish the whole quilt, plus the cushion cover and wall hanging to go with (two leftover blocks from the swap), and then sort out the frayed edges.
How useful are those binding tape thingies otherwise? I'm a bit reluctant to spend even more money just to fix this one thing.
