It's a little too late to be asking this question for my current class but I need to know for future reference. My first photography class only required 8 x 10 unmounted prints in a portfolio. However, my current class portfolio requirements are a little more complicated. Since September, I've been looking for a portfolio for my photographic prints. The requirement of the class is that they be mounted on 11 x 14 mat board. I've looked at various portfolios i.e. Itoya but all I've seen are whole sizes - no 1/2, etc., 11 x 17 is too long and not wide enough. The problem I'm finding out is that these portfolios are designed to hold 11 x 14 unmounted prints. I have a feeling that my next photography class is going to have this same requirement. Is there a source out there that makes and sells such a portfolios?
