[edit: argh..I fixed the link ]

I was looking at this post on image transferring
I want some horror movie t-shirts and since I'm poor I thought I could buy some soft shirts from Goodwill and use that transferring process

what was never really answered, though, is if there is
1. A way to make the image last longer
or
2. A way to get those same results a different way that would have the image last longer

Really, I just hate those basic computer t-shirt transfers and like the way these look

anything...and I mean ANYTHING that you think help me make some killer shirts would be mightily appreciated.

I checked the faq
and I read that whole thread
I swear!
