I've had an extra throw pillow for about a year with no cover on it so I wanted to splash a little Christmas here and there and this is what I came up with.
1 - 20x20" pillow
6 - 9x12" felt pieces (.25/each), cut into 2, 3 and 4 inch strips
1 - 30x30" piece of felt (used for the back - $2.99)
Sewed the strips together to make to panels for the front - no real pattern just as long as they measure 24". Sewed the two panels together, cut down the solid piece of felt for the back and sewed it so there was a raw edge and then snipped the edge to make the fray around it. Pretty easy and I am happy with it.
