I love putting together 8x8 pages. They go together quickly and can help when you are seeming to have a little bit of layout anxiety with a 12x12 page lol.
The idea that I got for these pages was that I wanted them to have the resemblance of photo frames so I put 6x6 coordinating pages in the middle. You can use smaller photos and see a little of the border or you can do two 3x3 photos in the middle and use the other two 3x3 squares as contrasting decoration, etc.
You can purchase these pages and more in my etsy shop :)
