Creat Attractive And Awesome T-shirt Designs

I want minimum 20 Tshirt designs it can be anything but it should look awesome & cool and also make duplicate of each of your designs for example if you created a design in white colour then duplicate it & change its colour to black so that it can be compatible with both light & dark colour. Have a look at below links to get an idea. All designs should be of A4 size.
