Tenugui is brand new to me but I still know it’s love. Makari Japanese Antiques in NYC has what looks like a sumptuous collection. More modest (but still very appealing) variations can be found at Tortoise General Store in Venice, California. Here’s Makari’s description of the cloth:

Tenugui is cotton cloth, used mainly as a towel, or head coverinig, was one of the most common house hold items up until a few decades ago,  when the terry cloth towel became popular.  Now they are valued for their aesthetics (because of the various patterns and designs), rather that for practical use.  they are commonly used now as Placemats or for decoration.
