I did this shirt with a Graphtec plotter and an opaque transfer using Avery paper (it's all I had available at the time when I got "the itch".

I wouldn't use Avery papers, tho).
This Is An Opaque Inkjet Transfer
I'm working on using the same method with IronAll Dark opaques. Not quite there, but almost.
Stay away from self-weeding inkjet papers. None of them are up to the task right now, unless you're using expensive sublimation inks.
