I just started quilting in January and I do have a question for ALL of you quilters....What type of batting do you recommend? I've purchased some at WalMart for baby blankets and it's really thin. I purchased a roll at an estate sale and when I quilted that baby blanket, the batting was so much heavier. So I'm not sure what kind or weight (if there is one) that I should be looking for. I prefer the polyester batting rather than cotton. Any input would be so kindly appreciated.
