Nothing wrong with making my own notebooks except I figure time ways it's cheaper to buy the buggers if you can find a style that suits. Easy enough to a point if you like buying Moleskine for their inflated prices, but I'm a reasonable man who like reasonable prices ;). And my pocket size is the same as your average man sized wrangler/levi jeans back pocket.
I'm keeping this notebook case dead simple Ed. I stick the notebook in my back pocket which is just not the place for a FP to be. My bush notebook case has a loop for a pencil and a pouch with a little penknife to sharpen the pencil with.
