I purchased a new Jobar 5 Piece Spring Form Pan Set at a yard sale. It's 10" diameter. It comes a regular 10" base and with a few other inserts/bases (with raised Santa, Bunny, Teddy Bear designs) that are about 9.5". I can't figure out how to use the 9.5" inserts. The band does not close up enough to fit them. Does anyone know how I would use these 9.5" bases?
