To clear up something that may be causing some of the headaches: you can, under very limited circumstances, sublimate on cotton. Specifically there was one specific ink developed to work on white 100% cotton. It only works on white, it's significantly more expensive, and it's a new product. I don't know precisely how it works, but I can only assume that it has an inbuilt coating that bonds to the fibres, and that coating is sublimated (so it likely wouldn't be true sublimation in my opinion). Personally I don't think it even counts, but it does exist to help make things more confusing
