Would these work for you?
http://www.beadfx.com/catalogue/findingsbaseearring.php
about a third of the way down the page (fifth row down), they have "
Findings - Earring - Clip-on - with Ring - Silverplated"
I shop at the "bricks and mortar" store all the time. They are wonderful in there. I would like to think that their online service is equally wonderful even though I have never used it.
Just a thought. I usually forget to put earrings in, but at the same time, I love earrings. It seems a shame to me that you make these pretty earrings but don't get to enjoy them yourself.
