Take your adult T-shirt, and cut off the bottom of the hem in a straight line across the shirt. The length you cut off should be the desired length of your skirt. If you need to measure, measure from your child’s waist down to their knees.
Place elastic inside the top of your skirt (at the raw edge), about 1” down from the top. Pin the elastic around the side edges and front and back. Note: you will need to stretch out your elastic in order to accomplish this, as the skirt will be much larger than the elastic.
To make the optional flower accessory, you will need a felt flower, silver jewelry chain and a safety pin. Slip the end of the jewelry chain onto the safety pin. Pick up a link about 12” away, and slip again onto the safety pin. Slip the safety pin through the back of the flower, and repeat with jewelry chain slipping the links through.
