Crocheted Roving Rug

This was my first foray into crocheting with roving and I used a plastic size S hook. This black shetland roving was made from fleeces that were a bit tender and hence had more noils and neps than I would want in a roving for spinning. The first rug was bath mat sized, originally measuring 21" x 35". After wetting (done in the shower) and washing with Charlie's Soap, I rinsed it in rain water and tumbled it in the dryer with no heat to get out the excess moisture, then allowed it to air dry. The finished rug is 19.5" x 31" and it is tighter and feels firmer than it did originally, although still quite soft.
