Gather all your supplies and get to an area where it's ok if paint gets on it

Put tape on the sides I the canvas so it'll stay white

Put random pieces of tape on your canvas. Make sure they go from end to end

Put drops of paint on cardboard or a paper plate

Paint all the squares and if you want you can leave one plain to write a message

Peal the tape off the canvas when mostly dry

Write in your message and your all done
