Now here's an easy project for you. You will need to buy a placemat for each kitchen chair to make a chair pad. I used square placemats - not rectangles. These are the same ones I am using for placemats on the table.
I have 4 vintage white kitchen chairs so I got four 15" square placemats and cut out 4 15" square pieces of fabric for the backings and a little more to make four tying strips for each to hold the finished cushion to the chair. I recommend a bodkin for turning the fabric strips - if you don't have one a large safety pin will work. I had a roll of batting already on hand so I cut from a four layer thickness four 12" square pieces.
