Thanks to an endless supply of sunlight in the summer months, we have some of the biggest dandelions growing near our house. As you can see, they are at least 2 feet tall.
When you pop the flower off the stem you see that the stem is like a hollow straw. You simply loop the stem into a circle and stick the skinnier end into the thicker end.... then keep adding more loops. The smaller ones made nice round loops while the huge stems created more angular shapes.
I knew it was a good idea to let those sunny weeds grow free.
