Size

As I read blogs it sounds like many of us are at the size phase. My plan is to make a hand painted journal and bind the 12 beaded pieces into the journal. I am leaving my material double page size then will fold it, seam edges and treat it the same as the other journal pages. To make the project manageable I will stick with 2.5 by 3.5. My question is can I lay out the pieces different each month? I am thinking that they will make the journal to thick and hard to bind if they always are the same direction and placement on the page. By alternating direction and placement on the page the journal will not have to be so thick. So my question is can I lay them 2.5 x 3.5 one month and 3.5 x 2.5 another, Robin what are your thoughts?
