This is an amazing design with great counterpoint shapes. The outside circle of the tree skirts is repeated in the shapes of the tree branches which counter the square of the background fabric and the presents. The candle in the middle represent the symbol of the star. It is another fold and stitch pattern which is composed of four units, which seam together at the trees to create an easy and amazing dimensional centerpiece that will surely become a family heirloom. Here is a great video tutorial.
