Turning Spruce

We had some spruce come down in our backyard in wind storms. I didn't keep a lot just a piece or two the sap is just too annoying and the wood is not that interesting to me. I just turned it to an even wall thickness for twice turning (10% rule), dated and marked it spruce, sealed the entire bowl, I let it dry for a few weeks on the floor and then threw it in an open box for at least 1 year. Spruce and pine have always been pretty stable for me at least. Also with the Anchorseal method I have lost very few bowls, I seal the whole bowl. The bag method may work but I don't like having to check and reverse paper or bags all the time.
