Area Rugs art the FFF

Here is a  photo of some felted area and throw rugs from the Fall Fiber Festival (2013) in Montpelier Station, VA, held this past weekend.   I think I just might try to make one (though all that work just for dirty feet!).  I think I will need some coarser wool than usual and a thicker batting.  I will also likely need to make it in the bathtub, due to the larger size.....hum, got to get planning!
