I have been making these for several years and did a lot of research on the batting. I used Warm Tater and now use the Warm & Plush as I prefer the thickness over the Wrap 'n Zap. Warm & Plush is the only batting I have found that doesn't have scrim - the package may say 100% cotton but, if you research it, scrim has usually been applied. And, I wash my fabrics first to remove anything that might be on the cotton and use 100 % cotton thread. I also enclose a warning that there isn't a guarantee that the item might not burn.
