I got to the point where I had TONS of paper scraps I was saving for my junk journal, and I figured out a great way to use them up. I glue them onto book pages while watching TV. Then, I have a whole book full of collaged backgrounds ready and waiting (and hidden and protected in a book). Here's how I do it and what I've made with the collaged pages.
I like to add strips of another book or old music - anything neutral and printed.
Then I add some plain texture. I like scraps of kraft paper or manilla file folders.
Then I add some colored scraps - all the same colors.
Lastly, I tone it down with some scraps of tissue, tissue paper, rice paper, or old tea bags. This blends some of the joints together and gives it some more texture. I don't think too much about these steps. I just slap them together as I watch TV.
I let the pages dry and then close up the book and store them in it.
When I want to make something, I get out a page and add stickers, ephemera, and stamping.
I like to make:
To make post cards, I glue half of a book page collage onto a cardstock post card. I trim to fit, ink the edges, and then collage on the book page.
Tag With Hidden Journaling Spot
To make a tag, I fold a collaged book page and half and decorate each side.
Then I add a tab to the top of one side. I leave the other side unglued so I can open the tag and journal in the middle.
Mini File Folder
To make a mini file folder, I fold a collaged book page so one side is about a half an inch shorted than the other side. I cut the bigger side into a tab so it resembles a file folder. Then I collage both sides
