My students have made walking umbrellas in two different ways. One year each child water color painted on a large sheet of paper. I traced a large umbrella on the back of each painting after it dried.
During a year when we had less time due to a schedule change, students traced a large umbrella on a patterned piece of paper. Then kids cut out their umbrella and cut legs from construction paper and glued them together. They look great as a display in the hallway.
This sample is from patterned paper. I do not have a picture of the painted example.
