Help please, designs on Nylon bags??

[buttercup1982]

I was wondering if anyone has tried to put designs on nylon bags?? I want to put a design on a waterproof nylon swim bag for my daughter. I was wondering if anyone has done this and how I would do it? Is it just the same as on a tshirt?
Thank you
