I wanted to share the resource "LightImpressionsDirect.com" They sell museum and art gallery archival supplies. They also periodically send out catalogs. The cover of their last catalog "New Styles of Custom Cut Wood Frames." One can frame a photograph for far less (and with museum quality standards) than your local frame shop. They also sell "OneStep Frame kits" everything is included. I have been using them for over 30 years. I also love their storage boxes, which I use to store photographs, and other non art items. Every Photography gallery I know uses their supplies.
