The Flash cup required a new design that I based off some old, classic Flash lineart. I added the lightning and used two different kinds of stain to try and make some contrast with the red background. It's still red on red but there's just enough contrast to make the outline stick out.
As someone who frequently sells handmade gifts I sure appreciate when clients put their holiday orders in well in advance. These dice cups are meant to be Xmas gifts but I won't have to worry about getting them out the door in the midst of the annual holiday crush.
