I think a pillowcase or tote, as suggested above, would be nice. I always wash my quilts first, they get dirty in the making, and to make sure all seams are going to hold up to washing. I do include washing instructions, but not detergent. As far as worrying about the care it will receive after given, that's out of your hands, once you decide to gift anything, then it's not yours anymore, so it will be cared for the way the recipient wants to. You are the one putting the work into making it, so you have to decide if they are "quiltworthy".
