Well, I checked my massive collection of notes and information and not once did the word “besom” appear. Clearly, this has been a gap in my knowledge!
I tried checking a couple of books, but so far, it seems @MeganB has more information in her pinky finger than the books I looked through did at all. (Over in Witches Dance - #44 by MeganB we learnt the origins and pronunciation of the word with her guidance.)
So I decided to skip straight to the practical for once. This involved consecrating my besom.
It’s just a cheap little thing I bought online months ago to have and I haven’t used it at all yet, other than to “set the (altar) stage” for a couple of spells and rituals.
I then tried to do a little sweeping with it and found that this particular one leaves lots of tiny little traces of fibre. So actual touching-the-surface sweeping is out.
However, I can still do some symbolic sweeping! But wait, apartments don’t have back doors. They only have balconies. Time to improvise a little.
I walked to the doors to the balcony and opened them to the night air. Then instead of some sweeping motions as planned, I went a little Ningguang (character name) from Genshin Impact (game) with it.

(Yeah, her movements are based on things. But I don’t know the words for them. 
)
Now, I’m already diving into flying ointment. I’m not going to follow the insinuations that some of these things are saying with where and how to apply it. I’ll also be careful with the ingredients. But it has uses I’m interested in, so I’ll see how I go.
Sounds like I’m yet another not super keen on besoms. But I did have a fun moment with mine anyway.
