I've been wanting to make a new boppy pillow cover to match the new baby boy's room since the colors in his room are gray, teal and beige. I used a simplicity pattern and whipped one up today. (If you don't have a pattern you could make one. You'll need tracing paper and a pencil to trace around the outside of your hoppy pillow and then add 1' for seam allowance before cutting it out) It was easier than I thought it would be! I cut 2 pieces of coordinating fabric, the back was two pieces to slid the pillow in and out through a velcro opening while the front was one piece cut on a fold.
Fold down the edges of both side of back pieces. One right side and the other on the wrong side. Next I sewed on the velcro and laid it out to make sure it fit.
I matched up the two pieces right sides together and sewed all the way around.
Flipped the material right side out through the velcor and stuffed the boppy pillow inside. Done!
