I have had good luck with most every brand I have. I purchased some off ebay and they came in little jars with no brand name on them. They worked well. If they are a really great buy, I say GO FOR IT. I have purchased ZING when I used a 40% coupon at Joannes. Sometimes they offer free shipping with a small order. You could try Hobby Lobby online, too. Or how about right here on Scrapbook.come? I think your best deal is to get a set. It's cheaper than buying them individually. Enjoy the heat!
