Mahogany is a good wood to carve in the round with, as long as you watch your grain. There are several types of Mahogany (a soft, a medium and a hard) I can never keep the names straight. The soft splinters easily, but if you take your time it works well, it's the Cuban Mahogany I think. The hard is really hard and takes detail beautifully, and has a gorgeous colour and works better with power. The medium....and I think it is the Honduras Mahogany can have odd strips of opposite grain running through it so pay strict attention to your cuts, and don't let them "run" on you. It works well with edged tools or power, has great colour, and finishes wonderfully.
So now the big question....what'ca goning to make???
