1. Fit your shirt, back side facing up, over the rectangular end of your board (not the pointy end). Moisten the shirt with a water-filled spray bottle if it’s not damp.
2. Finish ironing the back and flip the shirt over to the front. Pull the shirt down so the shoulder seam lies flat on the board and iron out the wrinkles. Repeat on the other shoulder.
3. Take the shirt off the board, flip the collar up, and lay it down so the back of the collar faces up. Spray and iron. Then fold a crease in the collar and iron it in.
4. Lay a sleeve lengthwise on the board and, pulling it taut from the cuff with one hand, iron it with the other. Keep it rotating so you don’t iron a crease into it—your sleeve shouldn’t look 2-D. Then open the cuff and lay it flat so the inside faces up. Iron. Repeat with the other cuff.
