Every designer wants to make a T-shirt at some point. The versatility of the medium allows for any style - there's always a niche to fill and something that hasn't already been done.
It helps that over the last few years the T-shirt scene has really grown up. Websites such as Threadless enable anyone to sell their work and get noticed, provided they have a good idea and a bit of know-how.
In this tutorial I'll explain how to create a T-shirt design that's easily reproducible at any print shop - or even at home if you have access to some simple screen-printing equipment. I decided it would feature a monster truck, which is bold and iconic, making it easily recognisable. This works in a single colour and I think my target audience will want to wear it. I'll also embellish the illustration with old-fashioned heraldic flourishes.
