Tools and Materials

• Front rib cage and back rib cage templates
• Scissors or craft knife
• Tape
• White T-shirt
• Cutting mat
• Repositionable adhesive spray

Rib Cage T-Shirt How-To
1. Print front and back rib cage templates. Trim first page on solid line and match to dotted line on second page; tape together.

2. Pinch front of white T-shirt at center of neck and pull forward, lining up sleeve and side seams, to create a fold down center front of shirt. Lay T-shirt flat on a cutting mat with this fold to the right.

3. Spray repositionable adhesive on back of front rib cage template. Place on folded front side of T-shirt, lining up vertical line with fold.

4. Cut horizontal rib lines with a small rotary cutter. Leaving T-shirt flat, cut curved areas with fabric scissors.
Tip: Swivel cutting mat rather than T-shirt to keep shirt flat.

5. Repeat steps 2 and 3 to create ribs on the back of the T-shirt, using the back rib template and lining up vertical line with back fold.

6. Peel off templates. Unfold T-shirt and wear over a black shirt.
