I have 3 vintage drapery pins. They are metal flowers in shades of blue, green and red.  The green one has a  molded plastic center. The green one is a bit larger than the other 2 and  measures about 2 3/8" across the front with the pin extending about 3/8" in the back.   The other 2 are about 2" across the center and same length on the pin. The finish is in fair condition with a bit of paint chipped off as shown in my photo's.
