This is a block that I made for a church quilt. I used an iron-on charcoal-colored bias tape and then hand-stitched it down. I didn't have a problem with it holding long enough for me to sew it down, but I only applied it as I layered the pieces--first the stained glass, then the ribbon, then the bird, then the perimeter. If I applied a lot of the bias tape at once, I can certainly see it lifting while I was manipulating the block. So I might suggest ironing it down a little at a time as the project progressed.
