As long as you get a good quality transfer paper it should be ok. I'm not sure of the ones I bought but i got 1 pack from Walmart and it turned the transfer pink, it was under a red shirt. The next batch I bought was from ACMoore and they were much better. Remember though that the transfers for dark shirts are white so where you don't have an image it will be white. Hope this helps! If not you may want try asking on the Creative Designs forum, they might be able to help. They are 7 forums down from us on the main page.
