click on the 'win a sample' in the lower right hand corner of the page, and then click on the pictures (any one, it doesn't matter) and then it will give you a place to enter your e-mail. Make sure to check your spam/junk folder for an e-mail to see if you won.
I won one (two nice size rolls in different patterns).
It took a while to arrive, but they DID send it!
If you can't use it, you could pass it along to a friend. I have a friend who LOVES these!
