Boppy Pillow Cover

I made these for my sister who is having her 1st kid soon. She bought a boppy with no cover, so she asked me if I could make some for her. I found this pattern online (click the link). It was pretty easy to make once you figure out how to piece the pattern together. It says you need 1 1/2 yards, but I didn't :S probably only needed a yard, and it still turned out the right size and everything. I don't know what kind of crazy way they were laying out their pattern thought, lol.
