I like 100% wool. I buy wool clothes at the thrift store on dollar day's (all clothing is $1 per piece) Thats alot for a buck! Then I take it home, take it apart, and throw it in the washer & dryer. It tightens everything up, and is perfect for penny rugs, quilts, etc. I have seen wool in the LQS, and it is $36 a yard, no way!
