Half Circle Spiderweb with metallic thread

Here's a spiderweb you see coming!  (No surprise ninja skills need to be used) 

NEW Version has a Metallic thread woven in the yarn!  Gives a perfect,  Spidery Sheen! 

 Made of white acrylic and rayon yarn, these Spiderwebs can be tied up just about anywhere! Approximately 2 feet across the top (plus plenty of stretch!).  Half Circle webs have 5 ties around the outer edge, to tie in place.
