Up arrow: thicker brush and with the really thick brush you can colour in the T-shirt a different color if you don't like the rainbow colour T-shirt already. Down arrow: Smaller brush (if you want to be detailed). Press C or green flag to clear if you did a giant mistake or don't like your idea. Space: to change colour of your brush all the colours of the rainbow and more.
I love designing, I might like to be a designer when I am older. I had the idea. My Sister, Shootingstar1 helped me so you could only colour in the T-shirt and not the background. I did everything else.
