I try to remember that once I give the quilt, it is no longer mine and I have no say in how (or whether) it gets used. However, I would much rather know that my gifts are being used and loved (OK, maybe not in a kennel), than hidden away somewhere.
I always make sure to include washing instructions when giving them, so that they know up front that it is OK to use it, get it dirty, and then throw it in the wash.
