I soaked my wedges in nail polish remover for about 30 minutes and then used a firm bristle tooth brush to scrub out the old paint. There are other ways but this was the easiest for me. let them dry and go crazy with the paint!!! 

Frankie:  go to the BV Vokey Design link at the bottom of this page and then click on the Wedge Works link.  You can custom order wedges from the Vokey website.  Good luck.  Let me know if you find it and what you decide to customize.

Search around this site for DIY paintfill.  There's a couple of threads with instructions if you want to do it yourself.  It's very easy.  I'm not sure if you can send in your wedges for custom action from Vokey, but rumor has it that a Vokey Custom shop is in the works. :)

The best quality and easiest way to paint fill wedges is to buy a paint pen from your local hobby store (Walmart works) and basically color in the areas you wish to change and then wipe off the excess with nail polish remover.
