I always carry a sketchbook with me everywhere I go, this is because as an artist/writer. ideas for stories or drawings are around every corner in life. I used to carry a little A6 sized reporters pad for these ideas, but the pad bent in my pocket, or got soggy from the rain. Slowly over time, the pad became so damaged that I didn't like using it. I went to the stationary shop to find a replacement, and I tried the waterproof paper (which by the way, doesn't work like you'd expect it to, writing and drawings still smudge, the paper just doesn't get all mushy) so I set out to build my own, version, not so much 'waterproof' but will protect the paper from getting wet from wet pockets.
Step 1: Getting Stuff Together!
It's a fairly simple Instructable to follow, and only need basic things:
-A4 Paper (I found in my area it's the cheapest kind of paper)
-Precision crafting knives
I made another one before that used wood glue, so the binding of the paper is completely up to you, this may mean wood glue, hot glue, or book binding materials would be needed instead.
