Holly is one of the best turning woods for detail with very fine grain. Turns so smoothly, finishes nicely. Easy to carve.
According to Dr Gene Wengert (WoodWeb) always cut Holly in the winter when the sap is down and the temperature is down. Saw into boards/turning blanks and sticker to air dry. Be sure to cut the pith out - holly will warp and crack easily near the pith. The cool/cold temperatures will help keep it white. I would coat the endgrain with Anchorseal. Doing this I've been able to dry holly and keep it whilte. Cutting and processing the summer I have never been successful.
Even if it stains you may be able to bleach it white after turning. Some people dye it black as a substitute for ebony/blackwood.
It also is wonderful for carving.
