A very nice piece of unused machine insertion Tambour or darn net lace trim in a floral pattern. Lace dates from the Edwardian - 1920's. A gold metallic thread is woven in with the floral and border patterns. If you look closely at the photo you will see the thread where it is woven.

Measures 3-3/4 yards long x 6" wide. Good condition although you may find some oxidation from storage.
