You go on to the tab to add furniture, click the inventory tab and scroll over to the hobbies sections, which looks like a chess icon.
Also I *think* you can get it in that hobby store on the town map but I'm not entirely sure.
It's more like you earned the right to buy a private wood working bench. They're in the hobby store, they show up once you earn the right to them. If you keep doing woodworking (clear the grid and start over), the next thing you get is the nice dog house (and that shows up in inventory, so it's truly free) and then a foosball table (also free). After that you get 3 LP each time you complete the set. I didn't know that until recently, my guys were doing woodworking just for simoleons, wasn't until I read here that if you start over you get more goodies!.
I think, therefore, I Sim! (Or I did before they told me to "harvest" them)
