Instead of cutting the thread, I use a small piece of fabric (folded in half to match my piecing) and run it in after I'm done piecing. I leave this in and when I'm ready to sew next, I just run my pieces through, finishing with another little fabric "tail" after I'm done. After awhile the little fabric pieces (I use muslin or scraps) look like some bizarre spider and I just throw them away. It's amazing how much thread I save & it keeps the tension just perfect, so I usually don't have a problem with the little thread bird's nests that can appear on the back when using the thread cutter. Maybe this will work for you, though it sounds like you are doing more embroidery type work than straight piecing. You are braver than I am. I haven't ventured into that part of my machine quite yet. :oops:
