In this article, along with the accompanying video, I'll be showing you how I built a modern cake stand from a slab of red cedar. I bought the slab from a local sawmill to ensure the wood was dry and so that I could start with a slab with two parallel faces rather than cutting the slab by hand with a chainsaw.
I always recommend buying locally, although there are also live edge slab dealers online. Typically, though, wood will be more affordable locally, plus you can inspect the pieces in person before buying them. I bought my slabs for $10 per piece.
