"is it enough..." - Don't every let another quilter hear you say that, you run the risk of being banned from your sewing machine for life and forced to donate all your fabric to ME. lol
Sheets!?!?!?!?!, geez, if you have one set on the bed and one set ready for sheet change day what pray tell do you need others for - get rid of the extras. Unless you're using them for backing (which I don't) they have no place in your life.
AS A LAST RESORT, STOP ORGANIZING AND START QUILTING, LOOKS LIKE YOU'VE BEEN SLOWING DOWN. But that's ok, as one who cares for her fellow quilter, I stand ready and willing to assume custody of your overflow. Call me.
