Guess I over did it on the size, but I envisioned it being larger. I'll tweak it a little in the morning and see what I can come up with. Thanks for the input, that helps a lot.
Still one color, made the small boot a little smaller, but still larger than original. Another color can be added easily if you decide you want the the two color effect. Did add solid black to the sole and tops of each boot.
Here are two more. One has a light shade of brown and the other has a screen of black to make gray. I know that you are planning on using these on cups. Wanted to show you both options for printing purposes.
