Cheap but effective Dark Tshirt paper for Iron on?

I bought these while learning how to properly size my images and whatnot and I was really very happy with the results, I have now spent two weeks with one of my first shirts testing the limits of what it's capable of and have now sent it through the wash 18 times and it's still looking great.

So does anyone else think these will work like avery or have another recommendation ? thanks!
