I have a Pfaff Expression 2.0 and use it on my handiquilter frame for free motion quilting. I would like to do some ruler quilting, example crosshatching and scallop work, on some of my quilts. I have both fmq feet for my machine, but they are not completely round. My question is: Does anyone know if there is a round quilt foot that will fit my machine, like the Hopping foot for long arm machines? I really would appreciate any help you can give me.
