Here is my sad large and well used heating pad. It gets passed around quite a bit at our house. And in the trip around the house the blue (ugly) fake flannel hot pad cover got lost. We've been substituting pillow cases since that but that is a terrible substitute for a heating pad cover.
So here is one of my 3 quilted roller shades that were in a bay window in my house. Excuse the really awful red ribbon. That is a different story but the fabric was rolled on a dowel and the ribbon wrapped under the rolled fabric shade and tied in a bow. I hated the ribbon and soon after I made the shades we remodeled the kitchen and these shades did NOT go with the tile back splash or the new counter top. So they were less than 6 months old when I took them down. It is just squares of fabric with batting in the center and the dots on the back. I put right sides together and turned it inside out to form the shade. Last year I made some hot pads and zipper bags with the other 2 shades. I blogged about it here. And that is a better view of what the roller shade looked like.
Back to the heating pad. I'd been thinking I need to make a cover for the heating pad for a while now and then I thought of the shade fabric. I wanted something a little insulated in the heating pad but not too thick and this was just the trick. Within 15 minutes the whole thing was completed since the edges were already finished. I took the lazy way out and stitched the top closed with larger stitches. I didn't have Velcro and snaps would be metal and might get hot. I thought about buttons to close it and then I just decided to sew it shut and forget about it. I can unpick to wash it.
One problem fixed!
