I make a bead-tailed dragonfly - like these
They have 4 glass beads for the tail - either round or square or even oblong and 12 -16mm in size but must be flat sided (ball shape doesnt work very well). More importantly they must have a 2mm hole through. I attach the tail by pushing a loop of .8mm tin coated copper wire through them so that means it is double and requires a 2mm hole for it to go through it.
I have lost count of the number of beads I have bought where the wire doesn’t go right through - in several cases out of 5 beads it only goes through 3 which means none of them are any good unless I mix colours where I can as here.
If anyone has any I would be delighted to buy some or can tell me where to buy them without beeing disappointed when the wire won;t go through.
