Sort of really love glue book even thou glue is one of those things I buy. I should really test some recipes and see if anything sticks (oh my goodness another art joke). I use PVA glue and have a gallon. Buy large if you have to, large containers will keep less plastic out in the atmosphere.
Yes Atmosphere, ugh!
Okay back to the book. Paper cut off from a print job. Always ask printers if they have extra paper. Folded into individual signatures, stacked for a even edge and clip. I use two credit cards with two binder clips.
I collect credit cards or gift cards, store cards. I just feel bad more plastic going in the trash.
Dye your glue if you want some fun colors. Add a little paint or powdered pigment to the glue, mix and apply to spine.
Let dry, then decorate cover as needed. I borrowed a few older pieces from my collage box. Everyone should have a collage box. Throw all your old cards in a box. Magazines pages that are interesting, artwork that doesn't work, basically a box of uncompleted thoughts, the collage box.
Write or draw inside for fun effect.
