Those are some fancy plans. They look nice. I usually use a paper sack.
I use to make drawings like that all the time. Design and drafting is a dying art. (Hell... Kids can't even write anymore.) Now everything is 3D modeling. So I like to draw stuff by hand as much as possible when I'm designing stuff for myself and even still sometimes when I'm problem solving and making field repairs for the company.
Making hand sketches is kind of relaxing and therapeutic for me, and it helps me think ideas through before I build things. So it's a win win for me.
