I'm wondering, is there a glue that will stay soft and flexible I could use? The part I glued is hard and stiff, and not appropriate for a lap quilt.
Do you have any other ideas? I've thought of sewing over it with invisible thread. I can't really quilt in that spot without ruining the design.

I've thought of a patch of a caterpillar or spiderweb or something.

It's important it looks nice because I am making it for someone else.
