Cut a big cloud shape out of thin cardboard.
Use a hole punch to punch three holes in the bottom of the cloud.
Cut three pieces of string and tie a piece of string to each hole. The raindrops will hang down from these strings and it's easier to do this step now then when it's covered with cotton balls.
Cover the cardboard with white glue and stick on the cotton balls until the whole surface is covered.
Cut a red smile out of construction paper and glue it and two large googly eyes to the cloud. Set it aside to dry.
Print our raindrop template and cut it out. Discard the center piece.
Trace the template onto black construction paper. Make three raindrops.
Cut a piece of contact paper that is bigger than the raindrop. Peel off the back and stick the template to it.
Cut the tissue paper into small squares (approx. 1"x1").
Use the tissue paper to fill in the raindrop. It will stick right to the contact paper. Overlap the squares as you go and it's ok if the tissue paper goes outside of the construction paper template line.
Cut a second piece of contact paper, peel the back off and carefully stick it on top of the first, covering the tissue paper filled raindrop.
Cut out the raindrop.
Repeat for all the raindrops.
Tape the raindrops to the strings hanging off the cloud.
Hang your finished craft in the window.
