I nake my own. Buy a small nose plier with round noses. The money you save will soon pay for them. Grab a piece of wire, hold it in flat nose pliers, twist around a piece of rod or wire- go completely around, snip the end right where it crosses the stem, and cut to desired length. I have made a jig with a couple of rods of different diameters sticking up from a base of particle board. If you have to do a dozen or more, a jig really makes it easier. I like painted ones, so I use black coated wire. However, if you want brass ones, brass wire is readily available. I get my wire at Michaels. HL also has a variety of small diameter wire also.
