A star in the sky

I visited the Washington Park Arboretum 2 weekends ago. Even though I’ve lived in Seattle for almost 15 years, it was my first at the arboretum and I realized what I’ve missed out all these years. Even in the winter, the arboretum was beautiful. I bet it would be even more beautiful in the spring. We found these paper stars hanging from the trees and I wonder how did they get there.
