I got this idea from Monique's blog and have been busily engaged on this project for gifts for special people. It has been a fun project, and it is even better now that I am all done.
Except for the ones for my own couch.
1. Get placemats that have different fabric on the front and the back.
2. Unpick enough of the seam to get your hand in and fill with stuffing.
3. Sew the seam back up.
4. Try not to look very closely at your bad sewing skills.
