My Son didn't want a bday cake (lucky ME!) he wanted "sprinkled donuts that look like captain America's shield"
I bought a cheap $8, 4'x8' piece of wood at home depot. I had home depot cut 2 feet off each board (so they'd fit in the mini van) so each super hero is 4'x6'
The wood I bought had a shiny side so I put a coat of KILZ primer down first so my acrylics would have alittle grip.
I printed a 4x6 coloring page of each superhero off the Internet and took it to a local copy store and had them copy it to a transparency. It was $1.25 and I could fit 2 superheros on each transparency.
I used a black sharpie when I traced the picture onto the wood. Sounds scary but It makes t easy to see the black lines under your paint
Put on one coat of acrylic paint. Once it's nice and dry retrace your lines with the black sharpie.
2nd coat of paint. Once it's dry retrace the lines again with black sharpie. The outline helps bring it to life. It also helps it look nice and finished.
