I received all of my wedding & engagement photo proofs in the 5x5 format since my photographer still uses medium format film. I was having a very difficult time finding frames until I went to Aaron Brothers. They actually carry a large selection of 5x5 frames. You have to hunt around the store for them a bit because they are not all together in one section but rather grouped with other sizes in the same style. They also have a great selection of Kolo albums - great for preserving your photos on archival papers The customer service is very good and their staff are always willing to help you find what you are looking for. Keep your eye on the Sunday newspaper ads for coupons.
