You guys all ROCK!
Well I just got home from the baby shower and I did go ahead and give the quilt. The mother loved it, the grandmother loved it, and as the gifts were passed around the room, most of the guests lingered over the little quilt to touch it and look at it closely. So I guess it was a hit, despite my apprehension... The grandmother (my friend) told me those were the mother's "colors", exactly. She said they were so NOT into traditional baby colors, they painted his room gray.
So, okay... Can't ask for better than that. I guess I'm just some kind of perfectionist snob that I didn't think the quilt was gift-worthy... Ha!
