Craft Knife/Self Healing Mat (preferable) or Scissors
Sprinkles of your choice
Ok, to start out with, determine what you want to stencil and print it out at the size you want it to be. I did a 2 in Poor Richard font, which came with my computer.
You have two options for the next step:
For scissors, trace the picture onto the wax paper and cut it out.
For a craft knife, tape the image to the mat, then tape the wax paper on top. Carefully cut the image out.
Now, gently place the wax paper onto the frosted cake and carefully push down and corners that roll up.
Cover the cut out in sprinkles, brush away the excess sprinkles and carefully lift off the wax paper.
Use a tooth pick to remove any stray sprinkles and smooth out areas of the cake that were tampered by the wax paper.
Too easy, right?
