I'm glad that you are now able to FMQ on your 401. You mentioned that you like the Elna Lotus SP better than the 401 for FMQ. I imagine that there will be a little bit of adjustment if the Elna is a straight needle. From what I've heard, when FMQ with a slant needle machine, you have to be careful to not move too fast since the needle goes into the material at a slant instead of straight up and down.
