okay, i ran into a problem...

 

   i blended one tattoo with the skin, and another tattoo with the skin.  when i went to blend those two together at 0.5, they each washed out each other's tattoo...!  the skin part of each blend is 'covering' the tattoo part of the other blend.  you know?

how do i do this right?  btw, each tattoo is blending with the skin in a different manner, at a different strength.  one is in colour, the other is plain single colour ink.
