Over the years I collected a large box of embellishments by shopping at large regional quilt shows. But, due to some mobility issues it's been several years since I have attended those. I don't know the vendors anymore who carried these products or if they still sell at these shows.
Embellished quilts were all the rage in the early 1990s, but they were usually pretty "artsy" for the time, or they were delicate florals with silk ribbon applique or "modern" crazy quilts. And most of all, they were wall hangings, not meant for lap or bed quilts.
"Honor" quilts are usually given as a "hug" of thank you and well wishes. Are you intending this for a particular person and know how they will use it?
