I have also seen ric rac on the seams -- the crazy quilt I have is a combination of fancy stitches, bits of lace and bits of ric rac covering the seams. The quilt was made for a VFW Auxiliary auction, my grandma scavenged many of my dad's ties and an old army blanket. The blanket was the batting, the backing is flannel and it is very, very warm. Each of the ladies pieced and decorated the 24" blocks any way they wanted, then assembled them and did the decorating over the joining of the blocks so it is obscured.
