alright sucking in my stomach here it goes.. I just use the foot that comes with the sewing machine. the straight stitch foot? there are others in that box but I dont ever know if I have changed them. will that make a difference with the stitch in the ditch? I havent taken any classes. yikes. I just put my machine on slow there are three speeds. If I put it on slow and watch close I am very close to stitching in the ditch most of the time. its tough and I have to pull things a bit if it gets full under the machine center arm? (dont know the name yikes) ok its a brother csi something another.. newer basic little machine. go ahead. tell me what that foot is called? I would like to do it better too.
