We have a rectangle lace with tulips across the bottom edge.  I'm wondering if this wasy lace for the back of a chair?  It measures about 18 1/2" in L x about 15" across.  The outer edges are a bit stretched out of shape looking with a critical eye.  If you can get beyond this or use this as a cutter it is a good item in nice condition.
