The bottom is chipboard that I covered in mudd puddles sand and shells. I used a pin to carve our names into it like you would at the beach. I added regular shells to the layouts too. The three shells next to the photo of us together is hidden journaling. You pull it out.
I used my cricut machine and lifes a beach cartridge to make the pink and yellow paper shells then I used stickles to make them stand out.
The background paper is blue but I sponged white ink to make it look more oceany.
