After creating these vintage inspired designs I have then tried to age them by adding various textures to the art work.
All the various textures were first added and then made transparent so that the colour of the T-shirt comes through, creating a worn and well used look to the shirt. Hopefully this has added to the retro/ vintage motorcycle T-shirt appearance.
I've used a a premium T-shirt for all these vintage design T-shirts. The premium Bella + Canvas 3001 is ring spun making it feel both softer and lighter and it has just enough stretch built in to make it much more suitable for wearing on the motorcycle.
