It would depend if you always use the same batting, or if you will use different battings for different quilts. I use whatever batting is best for that particular quilt, so I buy prepackaged batting. I prefer hobbs and buy from connecting threads when on sale, but I found an oops on Walmarts website that netted me 4 packages of 110"sq high loft poly batting for $11 total. I ordered 8 packages and made them honor the advertising (they have since changed the description). So I am currently full of batting!
