Melt candy. Tape sheet of waxed paper, about 14 in. long, to cake board.
Melt 4 oz. desired color of candy according to package instructions. Use EZ Thin, if necessary, to thin consistency of candy.
Pour melted candy on waxed paper. Spread candy thin using 13 in. spatula. Allow candy to just set, about 5 minutes.
Print out triangle pattern. Cut out pieces. You will need one full triangle and six smaller triangles for each tree.
Using craft knife and cut patterns, cut candy triangles.
Chill until set, about 10 minutes. Remove from wax paper. Repeat with remaining candy colors. Save candy trimmings for later step.
