The primary reference photo was this cover from the ongoing Hawkeye monthly, drawn by David Aja
Step-by-step tutorial below
1) Print a copy of the pdf chevron template that I’ve uploaded here. It should be to scale in landscape mode on an 8.5″x11″ piece of paper, but I’ve also included a measurement that shows how large an inch should be. Cut out the template.
2) Pre-wash a black cotton t-shirt. Place the template on the t-shirt, about 2″-3″ from the neck edge at center front. This template was made for a generic craft store shirt, size adult medium. It’s going to be worn by Mike, who normally wears men’s large t-shirts, but we wanted this to be tighter. The circular thing in this photo is my pattern weight.
5) Put a piece of cardboard inside the t-shirt, under where you are going to paint, to keep the paint from bleeding through to the back. Paint inside the taped shape using purple fabric paint and a foam brush. I used standard Speedball fabric screen printing ink, violet (color 4550) mixed with white at about a 2:1 (purple:white) ratio. You could also use fabric paint from the craft store, but I find that the screen printing ink is more durable in the wash. You will probably need two coats.
