I think only Pfaff lets you do that.....

I use one on my Pfaff too, but the knife on this one is not on the edge like mine. I quess that is for ease in SID.

Okay.

The Bernia has a foot like that #10. I use it for paper piecing. I never have used a foot for stitching in the ditch. I just eyeball it but it bears looking into with all these feet that I have.

The bottom one is exactly like my 1/4" foot from my Janome. The top one is a sid foot.

I've never heard of a stitch in the ditch foot and have always used a walking foot. Are you sure your not talking about a 1/4" foot?

I have the first one and I love it--it really helps me stay in "the ditch" and my stiches don't accidentally wander off the path. I think the longer one would be more difficult to manuver.

I quess that I am confused. I thought that you always used a "walking foot" when doing SID or other straight line top stitching or putting on binding since it allows both top and bottom fabric to move together. I do SID with my walking foot using invisible thread on top and matching thread to the backing on the bottom. the top stitches can hardley be seem and I just go slow and eyeball the "ditch".

I have both of these feet but prefer using my walking foot but that's just my comfort level :)

I have the smaller one, came with my machine. I don't really use it for stitch in the ditch, but it's wonderful for doing any diagonal work. Guides you right along.
