Make your own scrap paper notebook!
Step 1: Paper Gathering
Gather paper that is printed on one side. Scraps from a library or near a photocopy copier or printer is a great place to find scraps of paper that no one else wants. Try to find some heavier paper for the cover stock, possibly an old magazine or an outdated poster on the wall.
Step 2: Cut
Cut the paper in half (about 10 pieces of paper, to make 20 pages)
Step 3: Cut the Cover
Cut the cover stock you have chosen slightly larger than the paper about 1/4 inch up and down, and 3/16 inch in width
Step 4: Clipping
Take the paper and center it up and down in the cover and tap it so it all lines up along the spine.
Clip it together along the three non spine sides with paper clips or whatever else you have that might work (bull clips also work well)
Step 5: Punching the Holes
Unthread your sewing machine, using the handwheel to punch the holes along your spine. The longer the stitch length the better. It might be a bit hard to turn the wheel, but it should work. If you happen to have an industrial machine, it should sew right through it.
Step 6: Sewing
Now line up the holes from the machine. Thread your machine, and sew through your holes. Use whatever colours you want, I prefer to use different colours in the top and the bobbin
Step 7: Finishing
Tie the threads on each end, and dab them with a little glue on the knots. And woo-hoo, you have a lovely book to write stuff in, or even draw something cute in.
