I've never ordered from Clotilde's. Their shipping is rather high. April has free shipping and even if something is a $1 higher, the free shipping offsets it. Her FMQ foot is wonderful. I took my FM class at my LQS that sells Janomes. The instructor was very impressed with my foot.
That darning spring is a cool little deal. i wonder if the Elna would like it. She's very fussy about generic feet, but there's nothing to that one.
