I work primarily in Mesquite wood.  Mesquite is quite time consuming and works best with carbide tooling.  I save all the cutoff scraps as the wood is more than six times more expensive than red oak by the board foot.   I hand out the wine bottle holders and napkin rings as gifts to friends.  The wine bottle holder is a modification of a picture I saw in a magazine, I drew the holder full scale and then ended up “fine tuning” the hole in the holder to result in a bottle that is parallel to the table surface.  A 1 1/4 fostner bit seems to work best,

Napkin rings are bansawed, center hold drilled and edges rounded off on a router table.  Then hand sanded to P220 grit as is the wine holder.   Both pieces are finished in pure tung oil.  Mesquite has such a lovely reddish patina after a few months of exposure to air.
