The Stencil used for the hexacamo is from anarchy models. Be careful and take your time. There are many wrong ways to use stencils like these. It took a few minutes to figure out the best way to integrate these into my painting procedures. They are great for beginners and intermediate but the more advanced will find you still need your freehand stencils in conjunction to make life sane and simpler. I highly recommend sharp blades and sharp tweezers (and magnifiers for those of us whose poor abused Mk1 optics are becoming chronologically challenged)
Now...On to some rather enormous eldar craft!
