If you are interested in art quilts, the Studio Art Quilt Associates (SAQA) website has much to look at and delight you. SAQA is the professional organisation for art quilters. Online galleries are arranged by themes. It is an international organisation, based in the USA, and includes some well known Australian members.
Of course there are quilts for sale, news about art quilts, audio interviews with a number of artists, and an international calendar of actual exhibitions.
Well worth a bookmark and checking in every now and again - new online galleries are posted several times a year.
