I just did a search on these! Wow! These are attachements that go on the Janome darning/quilting foot. I sure would love to try these on my machine even though it isn't a Janome. The price on Allbrands.com is $19.99 so that isn't way out of range. BUT the foot that holds these are $50 for the high shank and $54 for the low shank...... These prices are on the allbrands site for those that are interested. I just searched for Janome feet and Janome free motion quilt feet. I shall have to do more searching.....
