Revamped heating pad

So you know how heating pads come with those plain baby blue covers? Mine was getting kind of rough looking after several years of use so I decided to make a nice new cover for mine out of some flannel scraps that I had lying around. It was just like making a little pillow case and adding some plastic snaps to the top. You wouldn't want metal because they might get too hot.

I cut a rectangle slightly larger than the heating pad. Then folded the short ends under 1/2" twice for a nice finished hem. I did it 1/2" so that the snaps would fit inside of it. I then folded the rectangle in half wrong sides together and sewed up the sides using 1/4" seam. Flip the case wrong side out and sew up the sides again using 1/4" seam to make a nice finished French seam. The flannel is also softer than the case that came with the heating pad.
