Antique & Vintage Laces Handmade vs. Machine Part 1
Real Handmade Point de Gaze Lace below: (notice the header or strip across the top) Tip: Handmade laces, and especially trims, often have a "header" so they could be detached from clothing more easily for cleaning separately. Machine lace trims will sometimes have a header, but not commonly. Some handmade laces have had the header removed, so this isn't fool proof, but it's still a good clue.
