What a cool tee to wear right now! You’ll need a T-shirt, scissors, elastic band, chalk, pins, matching thread & needle, a safety pin. Trace a line from the center of the neckline to about 1″ above the top of the seam of each shoulder. Cut along the line. Use the front as a rough guideline to cut the back as well. Turn your shirt wrong side out and pin a 1″ hem all around. Hand or machine stitch all around leaving an opening. Attach the loose end of the elastic. Insert it in the gap you left open and thread it all around. Try on the top to measure approximately the length of elastic you’ll need. Continue reading the instructions here.
