As a satisfied customer who has bought custom tee shirts in the past, I think Sticker Mule should consider expanding their clothing line to include sweatshirts, hoodies, and possibly hats. (Touques)

This might cost a little more, but, considering the quality of the tee shirts I've bought in the past, I think the price would be worth it.

Many is the time I put on one of my custom tee shirts, and wish it was a sweatshirt or hoodie, so I could model it in cold weather.
