antique net lace runner table set, tambour lace or embroidered lace

Lovely vintage lace net table set, three mats and runners in the same design. We've been told the this is tambour lace, but know very little about lace fabrics, and have no idea how to tell different types of lace apart except for knit or crochet lace! The largest runner measures 11" wide x 36". All three pieces are in very good condition, very little yellowing, no holes.
