These wood burls grow in pine trees ("knotty pine") and are used for decoration, in things
like fence posts or porch buttresses. Here at the Knotty Shop, they make all sorts of stuff.
I'd like to figure out how these burls form . . .

Inside the Knotty Shop, you'll find Alaska animal dioramas

and plenty of useless but neat gifts.
Note the knotty pine coat rack and the eagles made from moose horn.
