This video walks you through mixing your own tattoo gray wash in ink caps. Taking black Element tattooing ink you use a test ink cap to get your 'drip' then once you make sure that the ink is coming out correctly you let the ink drip into five separate caps. Each new cap gets one more drop than the last so the first gets one drop, the second gets two drops, up until the fifth, which gets five drops. Then you take your gray wash and fill up the cap. You can mix the inks with a toothpick or you can simply use your tattooing needle. Great way to mix your own gray wash.
