This is a really cheap option if you're looking to get a cool shirt to represent your gamer spirit. I do not own the rights to this and I don't sell these.
Step 1: Make a Skull Stencil
Google a picture of the ghost logo and print it, print it on cardstock or free hand it on cardboard.
Step 2: Optional Stencils
I made a really simple camouflage shape stencil and a fence stencil for extra detail.
Step 3: Pick a Shirt
I'm a fruit of the loom kinda guy, but find a shirt you can wear comfortably.
Step 4: Prep the First Layer
The first layer is the skull, very basic. I used an off white and covered my stencil edges in newspaper to prevent overspray.
Step 5: Optional: Add the Fence Details
Put your fence stencil on the right bottom and left strap. Paint and feather edges.
Step 6: Optional: Camo
Put the skull stencil back on and the camo stencil on and paint the lighter color. Put it on the opposite way and paint the darker color
Step 7: Optional: Weathering
Scrunch up the shirt and mist a dark grey or black on it.
Step 8: Sealing It Up
Put it in the dryer for 20 minutes to keep the paint from washing out later on. Now you're done, you've also saved about $15.
