Everything you need is at your local hardware store. It can be personalized and made as big or little as you want! The top tier I usually have a cake on so the nut and bar is covered (after I cover it with shelf liner so the food doesn't touch it). If you aren't doing a cake on top, you can usually find a creative way to camoflauge it. One more thing my dear hubby pointed out I didn't include in the picture, you should put a washer on top and bottom so the nut does not eat into the wood!
