Sketch book I guess

Filled to the brim with (mostly) daily sketches

Technically a take on the 1 drawing a day, but:
Its limited to only Monday to Friday
I have to draw the sketch during school hours
I dont have to do a drawing if its a holiday, teachers only day etc
Lazy drawings are fine

It ends either whenever I finish the book, or when the school year ends for my (from the first day until before exams begin, since after that I'm technically done.)
