Sketchbookum is a sub-label under the Objectum umbrella that describes attraction/bond to sketchbooks of any kind (this does include just “regular” notebooks used for sketching. If it’s a book you mostly sketch in, it’s a sketchbook.)! It can be of any type, be it romantic, sexual, platonic, alterous, and others.
