Kathleen, Hi, I live in Toronto too… The place I get sterling wire
is called Imperial Smelting & Refining Co. Ltd. They have sheet,
etc. too. 451 Denison (Markham, I think…) 905-475-9566
And I think they deliver, even small orders.
For findings, it depends. Lacy & Company at 55 Queen East
(416-365-1375) has tools, stones, findings, displays… They have a
site on line too… Sometimes they’re a bit expensive, though…
If you do a search on Google, more places for stones, findings,
charms, etc. come up. There is actually a hub that connects
jewellery resources but the name escapes me at the moment. Hope this
helps. Medeine
