This is a easy and quickly made project. I'm using simple tools that most of you already have. My cup is made from birch but you can make it from any wood. It just needs to be fresh cut.
Step 1: Tools you need
But the marking gauge and the power drill makes it easier.
The ax, the froe and spookshave are used to make the bottom.
If you don't have a suitable knife look at my instructable showing how to make the perfect carving knife
Step 2: Getting the wood
Step 3: The carving
Step 4: Carving the bottom ledge
While you make the bottom store the cup in a plasticbag so it won't dry out while your working on the bottom. You can all so store it in a bucket of water. Just don't let it dry. If you want to wait to finish the cup you can store it in the freezer until you have the time to make the bottom.
