I've got some old, crumbling trees on my lot which I haven't had the time or energy to remove. Now and again, they drop hollowed-out branches, which I've always thought have interesting shapes. I didn't really have a clear idea of what to do with them until I started seeing people making resin dice-rolling trays. It naturally occurred to me that I could combine the two. I roughed out some wooden rings by slicing a branch with a chainsaw, then dried them in the oven for a few hours, knocked out the loosest bits of decayed wood, and ran them through a planer. The wood got sealed with shellac, then I poured some green and blue tinted resin into it to make a floor. The resin has set up nicely, it's surprisingly lightweight (thin layer of resin plus very dry old wood), and I like the organic look. I've just made the one so far, but I may do more, possibly adding inclusions to the resin and switching up the color scheme.
