Take a trip to a local lumber yard where they have a HUGE selection of live edge slabs to choose from. This was a giant piece of mesquite wood, 92" long by 22" wide and 2" thick. Amazing.
While it was more expensive for this slab - $286 - it was nowhere near what I expected it to cost. The best part is that cost included them cleaning it up for me! Apparently, the bark will not last well on your live edge piece of furniture, so they removed the bark, any rotten sections and sanded it to 150 grit for me.
Already, I was so impressed.
