To assemble the body of the spider, I first punctured the bottom of the spider, the biggest circle, with the garden stake. I positioned the stake in the center of what would be the rear of the spider. Then I slid it through until it poked out the other end.
Next I secured the 6 inch circle to the 12 inch circle by continuing to pierce the stake through the 6 inch circle.
Finally, I did the same with the head of the spider. The stake was long enough to make it through all 3 pieces.
