Superior Threads
I purchased Superior thread Bottom Line for use in my bobbin. I sew on 100% cotton and wonder what would be a good top thread for quilt piecing. Botton Line is WT 60, very fine. I generally use a WT 40 thread on top for piecing but wonder if that will create a tension problem. I only use polyester or rayon for piecing and am interested in your recommendation.
Thank you!
