i would look for a museum with a reputation for having a notable textile collection. that brings the most interested viewers. also, think about a university with an art history or textile collection. a museum of american folk art is a good place as well. in the meantime, keep them under lock and key. have them insured for a limited time, just until you make other arrangements for them. would you like to keep them on exhibit near you? or does it matter? don't get them to take pictures. you take the pictures and send them to the society. no one has to know where they are and you needn't say where you have them housed. sad, isn't it?
