Sketch – Eyeglasses

I am taking an illustration course over the next few weeks and we are given daily prompts that we are encouraged to sketch. I pulled out my sketchbooks and found the various eyeglasses that I have sketched and combined them all here. I have been going to my sketchbooks first because I have so much that I have sketched over the years that many times I can pull something from there, first.

I really need to catalog my sketchbooks. I have over 100.
