A new notebook or sketchbook can be a bit intimidating. Especially if it’s a really nice one. All those blank pages! What if you mess it up with a crappy drawing, or you have to cross out & rewrite something?! And so you (or I, at least) never really get around to using it all that much.
These notebooks are not like that.They’re cheap & quick to make, & so you won’t really mind if your drawings turn out rubbish & your writing is messy. There’s no pressure to be perfect when you open up one of these.
It’ll take you less half an hour to make a pair, once you get the hang of it.
