Step 1: Patterns
then traced them in coreldraw, but you could probably do this in most graphics programs or do it by hand and use a projector if you need to enlarge it. I then sent it to my plotter to draw the pattern on paper, again you could do this by hand also.
Step 2: Cutting Substrates
Step 3: Carving
be very easy with the sandpaper, if you get to aggressive you start pulling out chunks, and finer grits are usually better
After carving is done put two to three coats of waterbased primer on the foam and let dry well,
you should then be able to paint with just about any paint without affecting the foam, but to absolutely
use water based paints throughout this portion of the project
Step 4: Cutting the Acrylic
Then get some vinyl scraps from your local sign shop and put it in you laser cutter (oops) plotter and cut it out. if you dont have a plotter or laser engraver get a sign shop to cut it for you or print it out full size carefully cut out with an exact knife after lightly misting the paper pattern and adhering it to the vinyl.
Step 5: Finishing Up
spray bombs. I then positioned the smaller acrylic pieces and used silicon to glue it down. I then glued down the carved hand to finish off the sign.
