This pinwheel centerpiece is perfect for party tables! The finished project comes sized at approximately 8-3/4" x 6" x 3" but can be sized to fit your needs. The file comes with the box base, the pinwheel insert (to hold the pinwheels in place), the pinwheel stems, the pinwheels in various sizes, and the center star pieces. The file is compatible with both the 8x12 and 12x12 mats. You can find additional images and a full tutorial on my blog: http://jamielanedesigns.blogspot.com/2014/04/pinwheel-centerpiece.html
