8x10 prints.....11X14 or sometimes 16x20 matte/border/cardboard/white thing....ALWAYS white. 11x14 prints.....16x20 matte 16x20 prints....don't remember, since it's been so long since I've enjoyed the use of a dark room. Always white mattes and bottom weighted (slightly more space at the bottom than the top) I prefer plain black frames...wooden or metal.....UV coated glass....acid free mattes. I prefer white because it tends to add just a bit more contrast to prints..+....I think the print should be able to stand on its own and not rely on some fancy colored mattes and frames to try and help it be somehow interesting......If I want to look at frames, I'll go to a frame shop.
