Does anyone use the "Snap Hoops" by Designs in Machine Embroidery for embroidery or using quilting designs? These are suppose to hold the fabric taut and your fabric can be moved without having to rehoop. I would think this would be a wonderful idea for quilting designs. I was thinking about purchasing the ones for my Brother PE700II but wanted to get some feedback...especially about the magnetic frame's strength in holding the fabric sandwich. I know the magnetic frame is not suppose to interfere with any computerized components.
