So I got one of my shots blown up to a 20x30 and now I am loking to frame it. What I'm thinking to do is to not have glass in front of the picture. Basically just the frame around the photo. Would it be best to use some sort of adhesive to "stick" the photo to the the backing? If so, what type of backing would I use and what would you use for the adhesive. This is the 1st time of doing something like this. Or would you just frame it without the glass? I think that if I were to do that, the picture wouldn't stay flat against the backing. Thanks everyone.
