Storing long lengths of webbing

I have a length of webbing my sister gave me for a birthday not too long ago and I'm wondering what is the best way or organize and store it so that it is easy to use when I need it. I don't want to cut it into shorter sections because I don't know how long I'll need to make long top rope anchors. It's probably around 15-20 feet long and I want to be able to coil it or something in a way that makes it easy to undo and set up again next time I need it. Any suggestions? 

Fold it in half (or tie it into a loop) and then daisy chain it like ​this​​​
