The design for the Frank Lloyd Wright Ennis House stone trivet was adapted from the Charles Ennis House (1923). The Ennis House was the last, largest, and most complex of the four textile block houses, having 24 different block forms, battered walls, and art glass windows representing abstractions of wisteria. Each Frank Lloyd Wright trivet is 7.875" square, made of original CoasterStones porous stone and is cork-backed to protect furniture and prevent scuffs.
