I've been trying to find ways to display paintings in the fantasy artist portfolio I will someday make myself when I came across this tutorial. I really liked how it looked when it's all done and it looks easy to add/remove/move pages while still displaying almost the entire page, plus the back-to-back display means you don't have to see the blank back of the sheet of paper. But I didn't like the folded look, that the corners could still flip up, or that the back stayed very tight together.
So instead of acheiving this with origami I made the elements seperately and sewed/glued it all in place. The corners that hold the postcards are sewn in the centre so everything stays in place very very well. I wasn't 100% on how it would look with the back of the accordian fold not held together in some way, without the postcards in it it bulged out too much and had no shape, but now that it's done it fans out so beautifully to display everything that I'm really really pleased. Experiment succesful! This will be perfect for my portfolio.
