So check me out! I decided to do something I've never one before and made my own sketchbook! It's about 8 1/2 x 5 1/4", just perfect to fit in my purse or whatever, and comes with a stylish hard cover that'll survive a lot of what I'm likely to throw at it. 48 pages.
I used this tutorial, and while I really like the cover setup, I can't say I'm fond of the binding stitch. I wasn't able to make it tight enough for my liking. So I'm probably going to see if I can modify this one instead for my next one.
This book's likely to get filled up with life sketches, since I'm getting interested in that these days.
