pellon makes/offers many different batts---which one are you wondering about?
there are cotton, poly, blends, different weights, density, loft...some are great (probably all are ok if used for the purpose they are made for) just read the packaging & quilt to the recommendations (if it says quilt every 2-4" then that's what you need to do-i've been quilting since 1976,,,never once have i pre-washed a batt...never once have i had one fall apart.
