I buy all the time from the states, particularly Keepsake Quilting, Hancocks of Paducah, Fatquarter shop, The Old Country Store Fabrics. One of my favourites is Be Creative Quilting Fabric. They are fantastic, the postage is well priced, fabric choices huge of over 8000. I live in remote NW Qld and we have one local shop, which I do support very well, however to stock up for later, its expensive at $28.00 per metre. With buying from the states, have never have had an issue, much quicker that sending something from Western Australia to here!!
Good luck and happy shopping! Also remember ladies, the more money we spend on quilting, the more are helping the economy!!
