I used this on a crib size quilt on my domestic machine. I found it to be super handy and did not cause strain on my hands. Very easy to use (haven’t yet tried it on round motifs). It also helped with tension issues I previously had when topstitching without it. I would highly recommend.
Sorry haven’t had a chance to use it yet as sewing room is under construction. Looks like it will be great though.
This item is great for smaller projects! It slips a bit on full sized blankets. That could be more of a user problem tho
