For all the regular carvers here on the site I'm sure you have you're favorite suppliers. I'd like to start a running list of prefered suppliers such as sawmills, paints, cork, carving tools or just general carving supplies and maybe even tutorials.
I took lessons from Willy at the duck blind here in Michigan. He sells pretty much everything you need for carving and has some great tutorials on his site.
