This question is really timely for me. I'm in the last stages of my baby Jane quilt. I have all the center blocks hand quilted and the pieced tris are also hand quilted (all QAYG)...but...I am just about to put it together and will need to do lots of SITD. Due to the size of the blocks and the numerous seams with PP...some of the "ditches" are really thick..I am thinking of doing that by machine. I just don't think my hands can tolerate doing it...so..I'll peek out the window before I start, but then think I'll go for it. You should too...
