For CRT we did colorblock landscape and I am going to tell you how we did it so maybe do it too .
So first we went on goggle drawing on your drive and then you are going to do a back round any color by the way. And then we used polyline and then you can colour it in any color and then we got some shapes and then we used some more colors and then we did some cool and random stuff like the stars and the sun /moon I guess.
