Snowflakes How-To
1. Photocopy snowflakes, reducing or enlarging them to be 3/4 to 4 inches.

2. Tape photocopies and then parchment paper onto back of baking pan.

3. Fill pastry bag with royal icing. Holding bag so tip is 1/8 inch above parchment paper, pipe icing to trace snowflake. Before icing dries, trace over snowflake two more times and add decorations with tweezers, if desired. Repeat for all. Let piped snowflakes dry 2 hours before painting or removing from parchment paper.

4. For a glimmering effect, mix pearl-dust food coloring with lemon extract (make small batches, since extract evaporates quickly), and brush on in a thin layer. Let dry, then use an offset spatula to carefully lift snowflakes from parchment paper. Icing snowflakes may be stored in a single layer in an airtight container for several weeks. Source
