The final promotional item that I designed was a Colour Tee. The process for this is shown below.
I started by downloading a tee shirt template. Then I filled in the outer surrounding area white.
I then coloured the tee shirts in the warm deep grey colour and placed the recoloured Indigo diamond design onto the front of the tee. I then added outer glow.
Using guides to align the diamond shape, I placed a duplicate on the back of the tee shirt, so that the design wrapped around the tee.
Then I added text to the back of the t-shirt, and outer glow to that.
I then drew out connecting lines from the graphic to the edges of the tee shirt and to the COLOUR text. After this, I adjusted the opacity of each line and added outer glow to those too.
I then placed all my promotional items (business card, wristband and tee shirt) onto an A4 document on InDesign for printing.
