A short note from The Connoisseur advising collectors on buying real black lace, especially Chantilly. It explains how to tell hand-made pillow lace from machine imitation by examining the edge loops or picots, and warns against "needle-run" lace, in which the net and design are machine-made and the outline is added by hand. It also describes a photographed specimen of old Chantilly, possibly a century old and made for exhibition, and comments on the fashion and low prices of black lace in 1905.
