Cyanotype is a way to make blue pictures. To make a cyanotype, you need two things: a piece of special paper and something called "cyanotype solution". With the cyanotype solution, you paint the special paper and then let it dry. Then, you put another piece of paper on top. In between both pieces of paper, you can put a leaf or something else with an interesting shape. Then you put the paper in the sun for a couple of minutes. When you take the paper out of the sun, you will see a blue picture of the shape on the paper. It is a cool way to make blue art without having to paint with a brush!
