This is a tricky thing to make (as they are very delicate and like to break!) However if you can do them, they look great. Make them c3 days before you need them, as they need that time to dry out fully.
This is from Peggy Porschen's Pretty Party Cakes book.
You will need:
Trex
Royal Icing
Piping bag
Ed Able art Hologram Glitter (I'm addicted to this stuff!)
Greaseproof Paper/ Baking Parchment
1. Draw out your tree designs on some white paper.
2. Place your non stick paper over tree designs, you should be able to see your design through the paper.
3. Very lightly grease the paper
4. Mix some Royal Icing to a soft peak stage and put in an icing bag. Cut end off icing bag to give a smallish hole.
5. Start piping outlines of trees
7. Carefully fill your tree outlines.
