Sauna Tonttu

Apparently every sauna, especially wood fired versions like ours needs a special tonttu to look after it and to ensure that doesn't catch fire inadvertently. Our little guy carries a bowl into which I put a few drops of aromatic oil from time to time.
The bad news of the day is that after avoiding it for the plague that it is, Covid has invaded us and we have both come down with it. No real idea where it came from.
