Carrying a sketchbook with me is a great way to jot down ideas for use later on. The only problem is there’s not many out there  that are to my liking without paying a hefty price for it.

A) It’s cheaper than buying pre-made.

B) I get full control on materials I like.

C) I get to make it in arbitrary sizes that they might not carry in stores.
