I have the Jamone Quilt Maker 15,000. The case that came with it is missing feet. I am trying to purchase these a little at a time but some of them I can't find and some that I do find and have purchased do not fit into the case. Does anyone know what the following feet are for: QV foot - I foot - and the STD foot . I am unable to find any foot with those Letters on it. If anyone else would like to know what goes into the missing slots, I have the list AP is the applique foot, FB is the Large Border Guide foot, U foot is the Teflon Foot, L-2 foot is the Bead foot and the H foot is the cording foot. Any help would be appreciated. Thanks, Cindy
