I have seen the advertisements for this foot but after reading the notes I'm not sure how well it would work for quilting so have not made the leap to purchase one. Guess I'm waiting until someone else tries it first!

It can be used for binding thin quilts with low-loft battings which are flatter and thinner (and NOT with battings with high loft, which are thick and fluffy). Because you DO need to feed the whole quilt sandwich into the slot of your binding foot..."
