One is a glorious use of plastic...trash. Cut up plastic bottles and discarded refuse strung to make a colorful presentation that once again highlights Anthropologie's mastery of making "something out of nothing".
The other is a more feminine version seen at Aerie (in the new Time Square 3 story American Eagle store) which uses fabric flowers to create garlands in colors and styles that highlight their spring campaign. It's fun, flirty and retro and adds a great texture to the store.
Go see them both and keep an eye out for more signs of warm weather!
