So I have to be honest, the way the Koi turned out totally surprised me!! I was happy that the colours blended well and then thought I would try to use the blender pen to make scales. And what do you know they look cool! Hahaha I'm lov'n the blender pen.
All you do is colour and shade your image. Allow it to dry. Take your blender pen and dab it on the image. The blender markers sort of suck the colour out as it dries.
