Cut out the 2 templates
Fold one of your 12 x 18 foam sheets in half and put your "crown" template on it. The folded side should be touching the folded side of your foam.
Trace your crown onto the foam board
Hold the fold really tight and cut out your crown. (It's like cutting snowflakes - we are going to measure once, cut once, and then unfold it to a larger piece.
Using the circle templates - trace the larger circle twice & the smaller circle once. (You'll have 3 circles)
Cut out all of your circles
