I received some beech scraps, so I made them into feeding dishes. The size is about 10cm to 13cm in diameter and about 3cm thick. There's a hole for a 16g Pro Jelly. If anyone needs one, please feel free to take it. *Beech is used in things like mushroom spawn bottles, but what about the wood itself? If you have any ideas for what these could be used for, I'd love to hear your comments!
