Several friends have asked me how I use the old-fashioned, black marbled composition notebooks as my gluey collage journals--books that contain a variety of daily musings, scraps of found paper, art experiments, and whatever else becomes part of the magical creative experience on any given day!
I'm currently on my third book, and although I keep a traditional artist notebook for more serious painting and sketching studies, I find that these composition journals allow me to play without a lot of "art" rules. It's a fun way to record events of the day, and it serves as a place to also play with color, geometric shapes, and possible design elements.
The first rule is... there aren't any! It's that simple. The pages will buckle, the glue will warp into tiny bumps, your pages may even tear if you get them too wet, but in the end, it all works out. So just chill... relax... and plop down those first couple of paper bits and add slap on some acrylic craft paint...
BTW: I use matte Mod Podge. It's a fine glue for this type of art. I usually have several old, thick catalogs that I use as blotters when gluing the backs of the collaged pieces, and don't forget to use an old, large, cheap brush for the glue--something that you can just throw out after a few weeks if it gets too stiff. If you keep dipping your glue brush in a bucket of water and rinse it out often enough, it will last quite a long time. If you rip some wax paper into sections a little bigger than your page sizes, you can slip the wax paper under your working spreads to protect the other page edges until the top paint dries.

(1) I drew some shapes with a pen, added some collaged papers from a magazine, and put some yellow craft paint on the left hand side. I did not prep the paper at all, nor did I glue any pages together. I don't mind the wrinkling! It adds charm.

(2) Next, I added some blue craft paint---still liking the yellow I guess...

(3) Decided to make the right-hand side more of a yellow ochre. After I did that, I realized how much I did NOT like the lighter yellow, so I painted over it. Then I chose to add the black animal skin looking design on top of the blue with regular black craft paint.

(4) I decided to make the middle area a baby pink color to mirror some of the colors in the collage on the right. I then found the word "pride" in my "box of words" (yes, doesn't everyone have one of these? :) and also glued some other magazine clippings of old coins on the topmost layer. I continued by adding black accents along the top and bottom edge and couldn't resist splotching some pink inside the black organic shapes on the left. For now, this seems ready for some journaling, but I could mess with it more if the urge strikes! We'll see how it ends up... stay tuned. :)
Remember, this is not serious art---it's supposed to make you happy. Use colored pencils, pastels, add ink... let your imagination be playful. If you don't like it, you can always glue over it again! :)
