All I mean to say is let your creativity be the frame. This is the picture I saw on Emmas blog where the photography of Warren Heath had been showcased. I just loved this one, as it shows a perfect way in which we can showcase our pictures and not let it go over the top as well. You can put all the pictures together in a collage with the shape of a heart, your heart. It will be so different and at the same time will also make up for all the wall art that you had intend to put up.
