If your t-shirt, already has a pocket, remove it with a seam ripper. If not, measure where you want your pocket to go.
Cut out your pocket using the original pocket as a guide. If you're using a t-shirt as your fabric, use the hem of the t-shirt as the top of the pocket, as seen below. I made mine about 1/2 an inch larger on each side since the original pocket was really small.
Iron down the sides of the pocket, and then carefully pin it to the shirt. Sew around the sides of the pocket with a straight stitch and then press.
