2 more weeks of my life. Someone asked how big these are and what I use. The size of each space is a little smaller than 2-1/4" x 4". My book is 8x8 square. I would have planned it better so a drawing didn't end up in the gutter but the book was made and then I decided I was going to use it for some drawings. oh well...next year I'll plan it better. The pen I use is a faber castell pitt pen in superfine. I like it because it dries super quick so if there is pencil underneath the pen, I can erase without smudging.
