To create a bookmark, design it with a computer program or use an existing program template and change the style, color and size of the document as preferred. Print the bookmark on card stock or another kind of heavy paper, then cut it out, and personalize it if desired.
Websites such as Creativity-Portal.com offer online printable bookmark templates. The 2-inch by 8-inch templates on this site come in several colors and are designed for printing on card stock. After printing and cutting, customize each bookmark using various craft materials.
Create bookmarks without a printed template by cutting construction paper or other thick paper into an appropriate size using regular or specialized art scissors. Decorate the bookmarks using markers, paints, glitter and other art supplies.
