3. Next, sandwich the rectangles. I used the dotted for one side and the green for the outside, and then used a dotted rectangle in the middle. To do this, I put a dotted rectangle face up on the table, put the front the green rectangle facing that, and then put a dotted piece on the top (the top dotted piece can face either way, as it will be in the middle of the "sandwich" and not seen). Pin the three pieces together- one pin in the middle worked for me.
4. Now sew three sides together, about 1/4 inch from the edges. Doesn't really matter what three sides you sew, but you have to leave one open to be able to turn the pad right side out. I sewed the two longer sides and one shorter side.
5. After all of them are sewn on three sides, go ahead and cut off all of the extra thread and cut any extra fabric off the edges, and trim the corners.
6. Turn all of the pads right side out. Push out the corners with a capped pen if you need to.
7. Now you will fold in the un-sewn edges.
8. After all of the edges are folded in, sew the opening shut- and so it looks good- sew all the way around the other three edges as well.
9. Cut off all extra thread.
