There is an article in July/August of McCall's Quilting about needles. Regarding machine sewing needles, specifically universal needles, the article reads "...for the precision work of piecing or quilting, a "Sharp" needle gives more consistent results on cotton fabric." In all my quilting reading, I had never heard this before. Do I need to stop using universal needles for piecing, and now use sharps? I haven't had any issues with univrsals, I change the needle after every project.
