I am reading too much I guess. I knew my "motif" looked puny and awful with regular C&C sew-all thread - not enough "umph". Then I read I should use topstitching thread- what a mess on the back - and trouble with tension, too. Surely I'm supposed to use a heavier weight thread than for piecing, but don't know which or how much I'll need. Help, please, from you wonderful, knowledgeable people. P.S. I also tried using two spools and threading them in the same needle and it looks better. Is that OK?
