First I picked up a couple of really cute, fun placemats from Kohls for around $1-$2. However I did not take a before pic :(
It needs to be double sided
Using a seem ripper remove a section of stitching from the top center of the placemat, I just made sure my hand could fit into the hole. Then I used some stuffing I had from another project and filled it. I pushed the stuffing away from the opening and pinned it down. Then I used my sewing machine and stitched it back up, but you could do it by hand just as well. I have some really elegant placemats that I don't let anyone use because they might get dirty. I think they might just become pillows!
