Woodcraft
Woodcraft has a good selection of pens and materials. I tend to purchase many kits from their local store in Toledo, Oh. This gives me a chance to see many of the materials first hand and pick the ones that I think will turn a good pen. I also took my first lathe class at the local Woodcraft store which got me hooked on turning pens. If you have a store near you, please stop in and see if they offer a pen turning class, it is an amazing amount of fun!
