About a year ago, my teenage niece suggested that O and I should read the Percy Jackson books. We share a love of Harry Potter, so she thought we'd enjoy them -- and she was right! O has been pretty much obsessed with all of Riordan's books ever since. I made him a Camp Half-Blood tee for Christmas and my niece loved it, so I took this opportunity to make one for her as well.

If you're new to freezer paper stenciling, start by reading through Rebecca's tutorial.
Open the text template and add whatever clip art you'd like, or make a separate stencil for the image. I chose a centaur, but other suggestions would include a pegasus, Poseidon's trident, Athena's owl, Zeus's thunderbolt, or the symbol of another Greek god. I used the Adonais font for the text, if you'd like to make your own stencil with a different layout.
Print and carefully cut out the stencil with the X-acto knife, making sure to keep track of the tiny negative space pieces. I didn't realize until I made this one that I'd forgotten the piece that separates the centaur's arm and arrow on O's shirt. Apparently not a big deal, since I didn't notice for over a month!
Center the stencil, iron it on, and paint.
The black covers well, so it only needed one coat in most areas. When you're satisfied with the coverage, peel off the stencil. It helps to use a pin and a tweezers to get the itty-bitty pieces off.
