In answer to a question about the fmq foot I use on my Juki. I’ve modified the foot so that it doesn’t “hop” and just skims the surface of the quilt sandwich. Leah Day showed this modification on her blog years ago and I’ve been thrilled with the results!!!!! See her video here. If you go 3:40 minutes into the video, she shows the purpose of the rubber band that I show on my fmq foot.
There must be enough contact with the fabric surface to prevent the sandwich from lifting when the needle comes up (or you will have skipped stitches!) but not so much downward pressure as to prevent smooth movement of the quilt “sandwich”. I hope this clarifies how this ‘mod’ was achieved, if not, please let me know!!!!
