The images were drawn by Ian Thomas, a freelance illustrator who studied Graphic Design in North Carolina. Here's what he has to say about his messy bun studies:
In the context of lecture classes, there's only so much one can draw from life. The subject I thought most interesting, and found had the greatest variety, was my classmates' messy hair buns. This is a series of ink illustrations inspired by the drawings originally done in the margins of notes, like so much of my work.
I hope all the other South Africans out there are enjoying their day off and making the most of the long weekend.
