I came across the term 「意匠ノート」as a type of notebook. Translated, I guess it would be a "design notebook," but I'm not sure what that means? A drawing book? A notebook with graph paper for architectural designing? If anyone has any insight, would appreciate it!
「意匠ノート」 doesn't means 'notebook for designer'.
「意匠ノート」means ... Notebook that have not only notebook feature, but also good looking (or / and) more useful design.
This notebook cut obliquely to turn the pages easily. ( for more useful design ) http://www.kokuyo-st.co.jp/stationery/campus_p/design/

Japanese stationery maker KOKUYO uses the word "意匠ノート" well. Those are slightly useful or slightly beautiful. (in Japanese ちょっと便利 or ちょっとかわいい ).
