like the gals said: it will lhold up a long time. remember that flannel does not last as well as a broadcloth.
i've used some crazy prints on my denium backs: cactus & coyotes-for a neice inAZ, bright and bold prints are fun. if you use a plaid with it....try to find a pantweight. keep your fabrics the same weight, so they will wear the same and be warm in all parts of the quilt., i found that homespun is too thin to use with broadcloth. it also lets the batting thru.
