Next we have to line it with some sort of water absorbent wood. The popular wood for lining is Cedar, but it imparts a taste to the cigars i would rather not have. After much Googling I found out expensive humidors tend to be line with either Mahogany or Sycamore. I choose Sycamore. I cut the Sycamore into 1/8 thick strips and laminated it to the Plum wood.
