To all the UK people on here. I'm looking to buy a piece of wood similar to american butternut. I have been told light walnut is similar. I only want this to do a trial using different oils to see the end finish as I have a special hand carved topper I want to make sure I don't mess up. As I say I will be throwing it afterwards so it does not matter it it has cracks or flaws or is even very thin or fat or very uneven.
