Thanks! I started with a matte, light yellow, then added matte red stripes randomly. My daughter used her craft Cricut machine to make me maple leaf stencils. I put a little double back tape on them to hold them in place and then randomly put them on the limbs in different directions and spacing.
I then painted the rust primer over everything and let it dry. I kept the stencils in place and put more stencils on, partially overlapping the existing stencils. I then sprayed some flat brown in places, which contrasted with the rust and the lighter colors. When I pulled all the stencils off, I got the layered look I wanted.
I sprayed a matte clear over everything and I'm very pleased with the results.
