I've never attempted to make an art journal or my own scrapbook but I have a strong motivation right now to take things out of boxes and drawers and give them the attention they deserve.
I made two journals...one for all of the cool little bits I've received from blog friends and one to store my Jane's Apron stuff that I want to keep (like postcards, business cards, and the first sewing pattern card I made).
For the basic construction, I started with heavy scrapbook paper cut to 8.5 x 11 inches. Then, without worrying about color, I folded the papers in half and nested them together. I used a paper piercing tool to poke 5 holes along the spine of the journal and threaded the pages together with baker's twine. I used 5 pieces of paper for each journal for a total of 10 pages.
There's also plenty of room to add more stuff. And plenty of other ideas in my head...I made 3 more journals to get some of my kids memories out of boxes and into their hands.
