almost as many choices in thread as fabric!! i have just started using Superior SO-FIne 50 wt poly for piecing, I love it. I have Superior Bottom Line, I LOVED using it to hand sew the binding - I like to use a doubled thread, and this just disappeared in the quilt. I like good threads, my machine does too - it doesn't like lint! I do my own machine and FMQ quilting, and am on the lookout for a bit thicker thread to use for that part. Ideas, anyone?
