Instructions

1. Begin by laying the t-shirt on a flat surface. Slide a piece of cardboard in between the shirt so that your bleach does not soak through the other side. You can just use a flat shirt box if you wish.
2. Take your bleach pen and try making some smooth lines on a piece of paper. This will help you figure out the best way to hold the pen and how much pressure to put on it.
3. You can now create the shamrock shape. Don't worry about a stencil - if you want, you can take a pencil and lightly sketch the design on the shirt first. We just moved slow and made the clover design you see here.
4. Let the shirt sit in an undisturbed place for 8-10 hours. The design will spread and turn bright white. The new clover will look about 2-3 times bigger than the design you made, so be prepared for it to spread out.
5. Once the design is dry, peel away any flakes of dry bleach. Rinse the shirt well in cold water and then hang and let air dry. It is not ready to be worn!
