Nor would I wash it. I've washed two quilts that I've given, one a baby quilt, which I would always do, and another to a friend and the reason I washed it was because I used Elmer's washable glue to sandwich it and wanted to get rid of any residue before I mailed it.
I've given others away without washing. I think it depends on you, and the recipient (if giving a quilt).
