Surprise! I know it's weird to see another post so soon after the last one but I just wanted to share a quick look at what I was playing with this week. When I was shopping at Sam Flax a few weeks ago I was admiring the accordion sketchbooks, or what some call concertina sketchbooks, and I was also admiring the price! I didn't want to spend that much on a sketchbook so I decided to make my own. I certainly have enough paper lying around the studio so I didn't have to purchase anything.
I used a full sheet (22x30) of 140lb Winsor & Newton watercolor paper. I cut two 8" x 30" strips from the sheet. I measured and marked every 6" on the two strips and then folded each one accordion style. Then I attached the two strips together to make one long one and glued the two ends to pieces of mat board that I had cut to 9x7 so the covers would be slightly larger than the pages. After the pieces were assembled I gessoed both sides of the paper and both covers.
