Hey there, I dug up my cookie tree kit and the instructions are for 2 of each size, regular sugar cookie dough ( gingerbread,rice krispies) and it shows the trees decorated , green with white "snow icing" ,all white decorated as snowflakes, red bow on top, and rice krispies with sprinkles.
All 3 use royal icing to "glue" together.
I am making them for my "group" and putting them in buckets with small cookies & candies around them. tied up with cello-paper and ribbon.
In my mind they will be wonderful...
Have a Merry Christmas.
