In fact, it may be an addiction. Some I ironed directly on (particularly garments already made).
But my preference was to make these cute twill tape labels...
Aren't they fun!
There are a lot of tutorials on these. And they really are simple. Just design your label on the computer and print it on t-shirt transfer paper. (Note: Test Print. After designing it as a mirror image on the computer, I discovered that selecting the t-shirt transfer option in my print settings reversed it by itself, and un-reversed all my hard work.)
Then cut and iron on your twill tape. Voila! No more headaches for other people... nor for the kids.
