Thanks, guys. I get a lot of my burrs from islewoods in Hawaii and from Australia. There's also a guy in Canada who has a collection of super rare and spectacular burrs, he doesn't sell them often, but if you get him to sell you one or two, he'll open up and sell more. Most of this stuff I've been collecting for years and just be prepared to overpay in bidding wars on Ebay. There's also a guy in the states who has a lot of rare burrs-burlsource.com. When on google.com, not .co.uk, search 'burl' not 'burr' and you'll find them. Be careful of some of the guys, especially islewoods in Hawaii as he is very, very good at varnishing and lighting his wood to make it seem more spectacular than it is, but he's still got a lot of the best stuff. I hope that helps.
