This is a hand made antique lace collar in an off-white colour. I am not a lace expert, but I believe that the lace is Honiton, which is a type of bobbin lace that originated in the United Kingdom. It is hand made and must have taken many, many hours to make. The collar is rounded at the back and measures 10 1/2 in width by about 13 1/2 in height. I bought this antique lace collar many years ago with a few other pieces, all of which were basted to blue paper with thread - this has kept the lace flat and well preserved. This antique lace collar is in very good condition with the exception of a couple of small brownish stains that should come out with the proper cleaning agent (see last close-up photo).
This is a beautiful antique lace collar - Ive included extreme close-ups, so please have a look, lovely!
