From there, I added a light string in 30 second icing (black) with a #1 tip and allowed to dry for another 30 minutes before adding the "lights" done in plain white 30 second icing with a #2 tip. The ornament balls were done with 15 second icing in red and gold and a #3 tip. The gold ornaments turned out yellow despite having added the "glitter powder" to the mix, so there is definitely some room for improvement there.
I'm really looking forward to expanding on theses with some additional texture using white sugar or using a multi-toned single color palate. Below are the trees in individual steps.
