Hello Rick, If the earrings are sterling, the posts should be
sterling. If possible, solder the post into a small hole you’ve
drilled somewhere in theback of the earring. Afterwards, hold the
earring in one hand and the tip of the post in pliars. Twist the post
back and forth a quarter turn about three times. This will work
harden the post making it quite stiff. Use silver wire about .8mm
thick and 11mm long or buy the heavyweight posts. Congratulations on
your terrific progress and the selling of yourart. Have fun. Tom Arnold
