We just heard from Lindsay about her great chair makeover: This was an old hand me down chair that I've had for about 6 years. I don't have a before picture, but the seat was stained and long past its due date...
...so I went to my local fabric store and replaced the foam with 2 inch foam, then attached the fabric to the wooden seat inside the plastic casing using a staple gun. I used Kokka Echino Ni-Co Scooter fabric (one solid piece).
We also found the Ni-Co Scooter fabric on Etsy in four different color combos ($9.50 for 1/2 yd). Fun stuff.
