I make it a point to be as " green" as I can with my designs as well as in my personal life:

-I use 50% recycled typing paper for my drawings and my printer.

-I Recycle all unused art scraps and typing paper.

-I offer recycled options on my business cards and other printed material.

-I re use my old ink cartridges and get them refilled at costco.

These are just a few things I do to try and be responsible in my business life :)
