Thanks. I ordered one of my creations on a black tee some years ago and was very disappointed. Your's looks very good. Perhaps I'll try again. Thanks for the lead.
The quality of the t-shirt seems good.
I had to resize my image quit a lot to be big enough, because you cant scale your original image as much as you want.
I also made a path around the "mouth/teeth" and removed the black background of the original image, and then saved it as an PNG.
Then it doesnt show the black square/background on the t-shirt, if you know what I mean?
