If you want a fantastic place to buy polish, contact Janet at Boulder Creek Boutique. Lovely lady and so helpful.
And check out the 'custom polish' (Thank you Cathy) that I made. Using the suspension base that Cathy sourced for all of us, and 'Sterling Silver Glitter Powder' from Coastal Scents I made an almost mirror polish. I'll put a few pics in so you can see how well it reflects.
