This is one of my ideas book that I made myself. It based on the notebook that I bought in the art shop in Israel long ago.
It's 1/4 of letter size paper (A4 for the other world). The covers are made of book cardboard covered with silver decorative paper. I drew pictures on heavy textured paper and glued them on the front cover - my favorite cat, words "ideas" and just tiny decorated strip.
Paper inside is rather heavy extra white printer paper.
The binding is a variation of Japanese stab binding done with a narrow satin ribbon.
I still have my previous ideas book not filled so this book is waiting its turn.
May be some day I'll make a little bunch of them for selling on Etsy.
