We ordered a few flannel pants for a party and also ordered transfers so we could add our party logo. Also order pre-cut transfers from Jiffy. Pants were exactly as seen on website and had no problem applying logos with heat press.
We used our jiffy transfers on several shirts, sweatshirts and sweatpants for our gym. The color we chose goes well with all our merchandise and we didn't have any issues doing it ourselves. So far the logos look great, even after washing.
