Used some leftover 1in purple insulation foam and a stitch ripper and a wee pair of sewing scissors. Pattern is a portion of a previous stained glass pattern I did.

I didn't use any adhesive backing because the craft store didn't have any and I was impatient to start. I can see how it would make it way easier, but it's very doable without it, just have to pay more attention to fabric tension.
