These are also laminated. Making them was pretty easy, following are the steps:
Paste snips of scrap book paper randomly on a card stock or in my case water color paper. I also colored my base water color paper.
Make an outline of the snips, I also added these stitches like lines, gives a dimensional effect.
next step is to laminate it, which will seal the surface. Use a thick transparent tape. It should be two times broader than the width of the bookmark.
Length wise wrap the tape around the book mark.
Trim any excess. Make as many as you want…!!
