niagara has always made "sizing" as a spray, as well. it's lighter than starch, and i always loved it for the hubster's work shirts--kept him looking pressed and "official" without chafing his neck. i've used it on quilts, and there was no build up. it gave the fabric enough body to be worked with without leaving it looking like a board. i haven't shopped for it for quite a while, but i suspect it's still out there. my stash of it is about gone, so i'll have to begin the hunt, again. i've never used best press, but niagara has served well--both the sizing and the spray starch.
