I have been wanting to try this idea for so long and I finally got enough time to do it. :)
The cover is made using my crayon paper. Both sides of the paper were covered in crayon. The inside pages are handmade papers. It measures 5 1/8 x 3 7/8 inches and is 1/2 inch thick. I think it would be perfect for altering by creating collages on the pages or painting or drawing on the pages. :) I am very happy with the results. It looks great!
