I just ordered more "feet" (lol) for my sewing machine and the SID is one of them. Hope I like it. Another is the 1/4 seam foot... I know I'll love it. I have done some SID without the foot and I agree that you just have to go slow. And, practice makes perfect. I haven't sewn in years until a few weeks ago and was really rusty when I first started back. I can really see improvement with time and practice, so don't give up!
