You would have to have an awful lot of different fabrics on hand to sell to the public. Look at quilt shops, how much they have and have to go "on sale" to get rid of it if it isn't liked. How long can you hold on to it for turnover, and if they didn't like it the first time will they come and look again? I sure wouldn't do it. Just my opinion. Just a bolt of Muslin is 80 or 90 dollars.
