These are the rocking chairs on my back porch. The fabrics are April Cornell. The matching napkins are used as cushion covers. I attached buttons to the cushions and then made button holes on the napkins to help hold it all in place. If you put buttons on all your cushions—placed right in the corners—then you can change out the covers very easily and frequently. Napkins are easy to wash too so when the pollen or diners soil them up=–then just change them out. Lots easier than washing the covers.
The napkins on the backs are just placed there to show you how it would look if you added a head rest. You could glue a button in place to keep the napkins secure.
