I remember these from when I was a kid. My mom ironed them onto shirts for me to wear, and a couple of washes, the rubber would crack, and they would fall apart. It was a shame, but now, you can use avery dark transfers (you have to turn the pictures over) and they will almost be like silk-screened transfers, if you get the iron hot enough. I have
several t-shirts that I have done that with, and they stay new looking, even after 20 washes. Try them, you will not be disappointed.
thanx for the share.
