You really need to try the Warm & White on your machine. I have had no trouble using W&W on my longarm, but find that it skips stitches when I use my Bernina Stitch Regulator. I've never had that problem with silk or wool batting, but haven't tried any other cotton/poly battings. (Before everyone tells me that Warm & White is 100% cotton - it isn't - it has a polyester scrim, 12% of weight I think). When I mentioned the skipped stitches to a Bernina rep at a national show, I was told that they had some others complain of skipped stitches with Warm & Natural and Warm & White. Howver, some other people have no problems at all. It really is dependent on your machine and how you quilt. Test first and you won't be sorry.
