I did some small experiements with the T-shirt format using a stock image and the outline of the design. I played with the positions and sizes to find the best look.
I prefer the centre design which displays the image large and eye catchingly. I also did a mock up using a black shirt.
Using one of my watercolour experiments I did a mock colour test again the white shirt.
I will be using T-shirt transfers once I have settled on my image.
