It's #44. I actually have #44C, but I think there's a #44, too, for older machines. It's also nice for its purpose, echo quilting, because it has circles etched in the cup around the needle so you can see an accurate 1/4" and 1/2" distance in all directions. If you forget the number and just ask for the echo quilting foot, they should be able to pull this one out for you.

Nancy, what number is the echo foot? I don’t think I’m familiar with that one. I have a foot obsession!

Nancy gave you great advice on the various advantages of the various feet. I agree with her.

I have multiple free-motion feet for my B-770 and use whichever is appropriate for what I'm quilting. My go-to foot is probably the open toe round metal foot. I can see well with it. If there is something on the quilt that might catch on the open toe foot, I use the closed toe metal foot. If I need a little more visibility around the needle, I use the oblong closed toe metal foot. If there is something on the quilt that is thick but I want to get right up next to it with the quilting (like some embroidery like twilling), then I use the echo foot which has a plastic cupped base that glides right up to things. And, of course, when doing ruler work I use the ruler foot. The only foot I generally don't use is the clear plastic foot that rides flat on the quilt like the metal feet just because, for me, the plastic seems to distort what's underneath it so I can't see as well where I am.

I'm interested in hearing opinions on the best free-motion quilting foot for a Bernina. What do you use, and why? I have a 750QE. Thanks in advance!
