This is something I'm very interested in! I have a few extra FMQ feet for my Janome 1600P and I know I could probably modify one of them. Great idea!
BillWest, I have looked at the feet designed by Westalee & spoke to the people at Pins & Needles in Middleburg Heights, OH about purchasing through them. As of last month they weren't carrying them. I have watched several online demos for your feet & may order online. It's definitely a niche to be filled for those of us who quilt our own quilts on a DSM.
