Next cut a piece of wiring about 8 or 9 inches. At about an inch from one of the ends of wire, wrap it around one of the sides of the round nose pliers using another set of pliers or your hands (whichever you find easier). Snip the excess wire off. This will hold your first bead in place. Try not to make it too big or it will be too obvious.
Now, start beading. I have shorter wine glasses so I beaded about 4 inches up the wire. If you have longer stems you might want to go another inch or so. When you get to the end, wrap the wire around your round nose pliers and snip off. I found that if you make them too snug, the wire will be more difficult to wrap around the stem so leave tiny bit of give, perhaps a beads worth. Enjoy!
