These miniature necklaces can be made for dolls as small as 1:24 scale. You can make them to stretch fit over the dolls head, or design them with a simple clasp system to take them on and off the doll's neck directly.
The necklaces shown here are made with Japanese seed beads, which come in a huge range of styles and colors to suit any fashionable doll. Here they are around the neck of my 1:12 scale ball jointed doll
