I have a ridiculous collection of notebooks and notepads, but my favorites are always those with a variety of mixed papers rather than all lined or all blank. Office papers, both new and old, are the perfect supplies to make your own mixed paper journals. You can easily fit lots of paper into even a small journal because the lined / graph / ledger / blank papers are typically quite thin. And, these papers are made for writing rather than patterned scrapbook paper.
Step 1: Fold a long timecard (or other thick paper) in half.
Step 2: Gather a mix of papers. I like to use mostly office paper because it is easy to write on, and add in a few pieces of blank cardstock and double sided patterned scrapbook paper for color. You can trim them all the same size, but I prefer the varying widths and lengths. Fold all papers in half.
Step 3: Use a sharp paper piercing tool to punch two holes through all papers, including the cover. The holes should be about an inch from the top and an inch from the bottom.
Step 4: If you have a sewing machine you can easily sew down the middle. I don't have a sewing machine so I just hand stitch the papers together with some embroidery thread and tie in the middle.
Step 5: Press your journal between a few books for a day or two so the cover and pages will lay flat.
Step 6: Toss your journal in your purse to jot down shopping lists and other reminders. Keep on your bedside table for late night ideas. Add mini photos and other ephemera to make into a mini scrapbook. Tuck inside a card and mail to a friend.
