I bought a large collection of Art Deco, celluloid hat pins/flashes. This groups are the black and diamante curved ones. I also have a lot of more geometric ones - and others that are not black. These can be worn in the Art Deco style cloche hats and berets - or anywhere else! I always provide a hat pin end so they are secure. Please contact me if you are looking for anything in particular. www.gillianhorsup.com or by phone at the shop - 02074998121. They range from £20 upwards.
