I started making t-shirts for friends and our boat club; it's slowly turned into a hobby that I really enjoy. I try to stick to Boating t-shirts, Camping t-shirts, and general Outdoorsy t-shirts.
I like to find t-shirts on the web and then make their designs better. It's a lot cheaper making my own than purchasing from some large chain site, and I have no problem passing those savings on along to you!
If you need something made I can usually produce a shirt in 1 - 2 days.
