I have used Documounts for many years, but they are now out of business. I prefer to order frames and mats to my dimension, especially the mat opening. I like to weight the mat opening, and not have it centered. What online company do you use for such custom framing?
I used to use Light Impressions http://www.lightimpressionsdirect.com/. Top quality and top price. But then I bought a Logan Mat Cutter and started cutting my own. Was amazed how easy it is.
