This is a shaded version of Pepper's clothes ref from his turnaround. https://www.weasyl.com/submission/1412725/pepper-ref-sheet I decided to turn this and my previous drawing of Chuck into "I Heart Bellies" pins for Further Confusion. You can see links to them on my Cafe Press.

For some reason, individual 2.25 inch versions of the pins (which is the pin size I sell at conventions) won't go up on my store even when I try to select them. The website must be buggy or something. But I'll try to have those size pins at FC.
