Baseball initial used styrafoam balls cut them in half and then decoupage plain white paper scraps to give it a different texture and look. Then I glued red Rick rack on and glued to a large letter that I got at Joann craft store.
Hula Hoop Tent Canopy: I used a 36" diameter hula hoop and 3 curtain panels from Target. I found a round dog bed from Costco for $26 compared to the $80 papasan cushion found on other pins. I covered the dog bed with an extra crib sheet I had.
