A shirt decorated with your signature is a very personalized piece, it looks like no other; so the supplies are a rope of the color you like (it should be something contrasting, I guess), a plain shirt, scissors, thread, a needle, pins and chalk. Draft your signature on the shirt with the chalk, maybe you can draw it some beautiful way, a monogram or something. Then pin the rope tight with needles. Now sew it on. If your signature is longer, than it’ll look also great if it goes all over your chest. Put it on and enjoy – now you look special and nobody has the same thing as you!
