I'm thinking of selling and making small sketchbooks and notebooks to sell online, possibly from Etsy and big cartel. I have been trying out a few different styles of binds and covers etc. This one is a Japanese Punch Bind, bound with the standard linen thread which has a pretty nice contrast against the cover. It's made with single sheets rather than folios (folded pages), so is a bit like a perfect bind with no glue.
This is a more standard three-hole bind of folios. It opens a lot easier so I think would work better for a sketchbook if someone wanted to lay it out flat to draw in. Both books are using a 160gsm paper, which is more on the sketchbook quality.
If anyone wants to buy one before I have opened an Esty shop, feel free to email.
