Query: Worked but a pain.

I had 13x19 matte paper and since they make a 13x19 book, but don't make 13" strips, I had to buy the 12" ones. They are totally non-movable once they touch the matte paper and it was a nightmare getting my pages to line up close to evenly. Ruined several prints and strips trying to get my portfolio put together. Might not be as bad on a paper with a higher gloss. Next time I update my portfolio, I'm going with the sleeves!!
