Rachelg, I had a quilt with warm/natural as the batting & was having all kinds of trouble HQ it. Someone on a quilt group that I belong to said it is very hard to HQ through W/N. I sat down & took out all of the stitching that I had done (it was really quite alot)took uot the w/n & replaced it with Quilters Dream Request. It is like quilting through butter. As different as day & night. I thought it was me as I hadn't HQ for 25 yrs & I thought I had lost my touch. I will keep the W/N for my machine quilting. Just a thought. Have you HQ using W/N before?
