Give the book a good sanding; pay careful attention to the fold because the paint does not want to stick there. Use wax paper between all the pages to keep them from sticking.
Mix your palette in containers with lids like baby food jars or yogurt containers. Your paints will keep about a week. With paint you get what you pay for. Paint is basically a binder (glue) and pigment (the colorant). Artist quality paints will give you a higher concentration of pigment. Binders are what the artist mediums are; they are the difference between fabric paints, artist paints, glazes and so on. Artist paints should not be used as a straight color, they are to bright. Always blend a few colors to tone them down.
Tinted gesso - lots of gesso and a little artist quality paint, use at least two colors. Glaze - 1 part acrylic medium (gloss or matt) 1 part water and paint. Add mica (Pearl Ex) for sparkle. Molding Paste – mix with a few blended colors of paint. Tar gel – Mix with paint or mica powders
Next paint the pages with tinted gesso. Let dry. Apply a second coat and run a comb through it or stamp into the gesso. Let dry. Using the glaze or tinted gesso glue things to the pages of the book to give it texture such as gauze, dry wall tape, and lace. Use molding paste to add texture. Highlight texture by lightly rubbing with full strength paint. Use Glaze to glue paper to the book page so it becomes part of the background. Sand off some paint to give more texture.
Now that you have a great background, what to put in the book? Anything and everything, anything you would glue on a card, scrapbook page or saving for that special project.
The book has now become a sculpture, to be displayed standing up, it does not need to close! Thick 3D stuff - works great. I like to keep my covers simple so people can hold the book comfortable to view it.
