That is nice.
I have to revisit shellac next time I turn cedar. I tried it once with bad results and hadn’t thought about trying it again.
You didn’t hollow it, but if you ever do another, have you thought about using a forstner bit to drill out the center to outer potpourri or cedar chips is? I wouldn’t try it on this one now only because of the knot.

Anything worth doing is worth overdoing.
