Cat, I checked out the site you mentioned above that carries Trinity Brass - thanks for the link. They appear to have the same clasps as Vintaj. To me, these are expensive, just about as expensive as Sterling. The copper toggles I bought were maybe 75 cents a set, so I can make some $15-$20 bracelets and still make a profit.
The sterling, pearls, swarovskis and high quality gemstones will be my "elite" line, and the brass and copper will be my "economy" lines.
Last night, I counted all of the brass earrings I've been making over the last 3 weekends, and I counted 65 pairs! Some are for the rummage basket, and others took more time and effort and will be priced higher.
Now it's time to move on to some copper jewelry, and a bit more of the "elite" line.
