If you want me to make you an iron-on, send me an email with your artwork saved at 300dpi, sized to the dimension (inches) that you want (jpg, gif, bmp, etc). Dark shirt Iron-ons work best if it they yave a dark background, but you can see with the GGG heart, I outlined it in white to help the dark red arrow stand out from the black. Light shirt iron-ons need to be reversed and on a light background.
