All of my albums are 12x12 3-rings and I scrap all 12x12. But within the past year or so, I've been seeing many more 8 1/2 x 11 pages or similar. I keep saying I want to make some, but when I sit down to scrap, it always ends up being 12x12. I would need to make a conscious effort to scrap a different size. But if and when I do get around to doing it, I will just mix the different size pages in with the 12x12 ones in chrono order, however they fall.
You know, I've been suddenly seeing more 8.5 x 11 pages here and there as well. I have read that many scrapbook magazines feature 8.5 x 11 pages because they fit more easily on their magazine pages. I think you would love 8.5 x 11 landscape orientations Michelle. I did that for my daughter's wedding guest book photos and really like the way it looks...(more than the upright 8.5 x 11 orientation).
I would prefer not to have to scrap 8.5 x 11 but I have all these albums in that size that I need to use somehow. Funny how you get used to a certain size so quickly!
