Color Your Own Beading Thread UPDATED

Someone mentioned this on Facebook (I'm sorry, I don't remember who) and said that Meredith Willet of M's Canvashouse and Elizabeth Turner Designs recommends this technique of coloring beading thread.  Please note that the person at Beading Daily is a jewelry maker who uses a braided beading thread, not floss or the brands of beading thread we are familiar with through Sundance and our local shops.  I would assume that you can color any beading thread besides the braided but I don't know that for a fact and of course some colored threads markers won't do much to change.

UPDATE:  Vicky DeAngelis is the person!  Here's what she said in the Comments section of this article~
"That was me Jane...and you might want to mention that it is not just any colored markers, they are Sharpies. And the thread should be waxed."

Thanks, Vicky!
