Place plastic inside the T-shirt to protect the back from paint. Protect your work surface with plastic and lay out the T-shirt as evenly as possible. Print out the text "look cool" from our PDF and place the printout inside the t-shirt, so that it can be seen through the fabric. Use the printout as a template so you know where to place the dots. Use a flower stick or another narrow, round object to make the dots in various colours, following the text. Let the paint dry and fix with an iron according to the instructions.
