I use 2 1/2 binding on my quilts with minky backing. Worked fine for me. I sew the binding to the front and then hand sew to the backing. Actually, I use 2 1/2 binding for most all of my quilts. Have tried the 2 1/4, but prefer the 2 1/2. Since I always seem to have plenty of binding left over, I decided if it was all 2 1/2 I can use it as a bonus sometime, either as binding or cut up for a scrap quilt. Dreamer that I am, I haven't made on scrap quilt yet but you never know when I just might
