I just discovered a dip pen and ink that I bought way back at the start of my course, and then promptly forgot all about and didn't use, in the back of the cupboard next to my desk, so decided to try it out... Wow! I love it! The variation in line-width adds an interesting element to my drawing and I like the added density of the ink. I played around with it for a while, scribbling and mark-making, and drew a quick self-portrait reflecting my recent mental state (brain-fried!).
I'm eager to experiment some more with this new (to me!) method of drawing!
