Where do crazy quilts fall into this? To me, a crazy quilt is the ultimate scrap quilt, but that might just be me.
What about like a jelly roll race quilt. Is that scrappy? Each piece is different... Does it depend on the jelly roll?
I think I (more or less) lean towards thinking the same way you do about those two words, Bear. Although I think my style overall is "scrappy" (why use just one blue when it's so much more fun to use six?) so I probably don't use that word often, that's just a "normal" quilt for me.
