I hear ya. My jewelry magazine collection has Gold, silver, Swarovkis, lampworked and everything else! Most of the time, no one in Australia stocks what is seen in the American magazines. Or they only have very limited stock, its expensive, or its sold out! And by the time it comes back into the shop, I've gone and made something else that doesn't involve those components.
I wish we had more variety like in USA. It is kinda sad though. All the magazines and books say to use top quality materials like gold filled and such, but as a beginner myself, I find it off-putting when someone says, I should have used gold and silver and Swarovski crystals. There are alternatives out there, that do have the same sparkle as a Swarovski crystal but with half the price tag.
