Is it nosy to look in other people's sketchbooks? Probably, but I do love a peek myself, so if you're interested (or nosy) here's a peek inside mine.
TOP TIP ALERT! I used to (until a few weeks ago) use loaaads of different sketchbooks at the same time, one for each project kinda thang. This inevitably results in never having the right one with you at the right time and then spending ages looking for it and then deciding you need a different one now anyway. So don't do that. ONE is good. This has been a public information paragraph!
