Use the foloowing tips-1) Use spray basting- makes quilt lighter and since it "glued" together the sandwich will not move aso you can start on any side. 2) use invisible thread for SID -you can not see stitch as easily so not see crooked lines 3) be sure entire quilt is suported well - do not let the quilt hang down since the weight of the quilt will make moving quilt harder and make the SID crooked.
