Thanks for this link. It's great information. I learned that the needle and thread size are the most important factors in quilting, especially for free motion quilting. I recently switched to titanium coated needles. They stay sharp much longer than regular needles so are a better value for the money and my stitches look better too. I never buy needles off the rack unless I have a coupon. I buy most of them online. I like Organ needles the best and Schmetz needles are excellent if your machine likes them.
