My girls actually had fun with this one. It just took longer than we thought. All you need are straws, ruler, scissors, and tape…easy peasy!
Place a straw along the top of the four triangles and tape around the straw and the point of each triangle. Do the same for the other set of four triangles.
Here are the finished products. 🙂
