Use a ruler to draw a straight line in the full length of the cardboard. Draw another line 1/2 inch away and repeat for a total of 6 half inch sections. Repeat again using up the cardboard.
Paint the first line with purple color. The next line should be blue, and the next is green. The fourth line is yellow, followed by orange, and finally ending with red.
Cut a raindrop shape out of another piece of cardboard or from paper, making the widest around about 3 inches. Trace the raindrop shape onto the rainbow lines. We got 8 but 6 would be plenty. Cut the raindrops out and set aside.
Use another piece of cardboard to draw and cut out a cloud shape. Cut different sized circles and ovals from white felt. Use white craft glue to cover the cloud with the felt, overlapping as you go.
Turn the cloud and the raindrops over. Cut 14 inches length of string for each raindrop. Tape a piece of string to the back of each raindrop. Next, tape the strings to the back of the cloud at varying lengths.
