Ekowool has been some of my biggest posts to date. Now you have the ability to try it for a very small investment. This seller on eBay is selling 2mm from 1 - 12 feet long. If you haven't tried it - its a $2.45 with free shipping.
If you already love it - here is an opportunity to get it at a good price in large amounts.
I tend to sell these guys out pretty quick - so get in on it while you can.
