Hi flipperjane - excitement huh! What deck are you getting?
Some of my round decks just give upright meanings - Songs for the Journey Home for example, and Motherpeace - and I think you would just turn them upright as you lay them down.
Some give reversed meanings as well, but treat them as if they were rectangular cards, they're either "up" or "down".
At least one, The Star that Walks Around, talks about the "progression" of the card, talking about Moon phases and seasons.
[I could copy out that relevant section if you want]
Basically it's seen as an added element of the card, is it "coming into being" "full and happening now" "passing away" or "hibernating" all things like this.
I think you would have to look at your own cards, and what the deck creator might have written, and see what feels right for you. Do a few practise readings, and see if you feel you want to create nuances of meaning. This is a fairly unexplored area I think, so you really are free to make up what works for you.
you'd need to keep notes though I would think, at the beginning, whilst you and the deck images sort out what you want to say.
For myself I tend to only read upright, with the occasional "smack on the side of the head" from a reversed card that obviously wants to be noticed - these ones usually make me laugh in their directness and irony.
Do keep this thread going with how it goes for you won't you? I'd love to know what you find works well.
very best wishes

p.s I will check out the LWB with the rest of the circular decks, just in case someone had something else to say.
Not sure who else uses round decks regularly.
