Also try to search on e-bay, but note that the quality can be suspicious, especially if they are made in China

I've often wondered if you could spray paint them with enamel spray, the type that is used for cars? You would need to experiment and see if it has staying power though, just a thought.

Vena Cava (www.venacavadesign.co.uk/), Corset Supplies (www.corsetmaking.com/), Farthingales (farthingalescorsetmakingsupplies.com/), and Lost Coast Historical (www.lostcoasthistoricalco.com) should have you covered for the basics - black, silver, brass. Beyond that I don't know of any sources offhand. Dritz makes colored grommets but they're the cheap split back kind and will snag your laces and tend to be weaker over time.

Where can I purchase coloured grommets to match my fabrics please?
