I recently hand quilted 100% batik quilt with W&N batting. I use either #11 or #12 Roxanne's. #11's are definitely easier to thread and a bit stiffer than the #12's. But if you need really fine needles the 12's might work for you. Just make sure you get the Roxanne threaders if you're going to use #12's. Normal wire threaders will NOT fit through the eye of the needle on the #12. I can thread #11's without a threader using hand quilting thread.
