The set isn't technologically complicated, but looking at it inspires thoughts that are something along the line of "why didn't I think of that?" It's a series of cookie cutters that gradually decrease in size. When these cookies are stacked on top of each other, starting with the largest, the result is a cookie tower that looks like a traditional Christmas tree.
If you're like me, then you'd be happy to make a tree out of cookies as a solo activity. Or, you could do it as a family and have everyone decorate different layers. In either case, you're going to have a much cooler centerpiece on your holiday dining room table than anyone who decided to go with a snowman candle holder.
