The rug in the picture was made from old sweaters, that had been unravelled and then crochet into a rug. There is nothing better to place by the door - it not only offers a splash of colour to the entryway, but is absorbent, keeps most dirt of the floor and best of all, it's easy to wash. The re-purposed wool will serve as a rug for many years.
I know many Hutterites make gorgeous rugs with new wool and use intricate patterns, and I love those as well. But I'd rather see something old become something new.
