Hi Jon. Cant give it all away but I think I share just enough! A DC/PLS print would'nt work as the plastisol would act as a resist BUT..........if you did a major choke on the top colors then it would, creating a halo effect. If you distress enough you could emulate finishes such as Batik. BTW when doing waterwash and slurry sprays be careful not to over saturate, especially on sheers and fine gauge ringspun, or else you'll need a slip sheet in the garment to protect the back of the shirt.
And very funny Pierre
