I bought a pair of 14″ x 14″ zippered cotton throw pillow covers a couple weeks back from Sublime Stitching and finished the first one this afternoon. You can get plain pillows in all shapes and sizes at Hobby Lobby, and I easily found a couple that were the right fit.
The embroidery transfers were the set on Sublime Stitching designed by artist Julie West, I used most of the motifs. The sun was actually a flower, but I thought it made a better sun, so I trimmed off the stalk and eyeballed stitching a complete circle. Came out pretty good!
