1. Choose your stencils and plan your design. Alternatively, find pictures you like on the internet, and draw them freehand with a water-soluble marker. (That’s how I drew the tree illustrations.) Fill in the stencils (or outlines) with permanent fabric markers. The colors mix together just like dyes, so try blending shades. The dyes are permanent without heat setting, but let them dry for a couple days before spraying or dabbing with water to remove any visible erasable-pen marks.
