Here's an easy-peasy idea for making a small pillow. As you may know I love re-purposing cloth items -- shower curtains for wall art, bedspreads for tablecloths, etc. This project involves making a pillow out of a placemat. This only works with a double-sided placemat. The one I used is $5 right now at Pier1 Imports.
One end of this placemat is topstiched. Use a seamripper to take out those stitches, thereby opening one end to insert the pillow. I used an 12" x 20" feather pillow insert from Hancock Fabrics.
