Always a good idea to leave a little room for chaos! If we can have days off and vacation days, it makes sense to me to let the cards/runes have their days off too. Sometimes fate is in our own hands! 
Thank you, Tracy! 
I’m seconding you on this, Nikki! It’s been enlightening hearing from you and everyone else about how you read. I do think this is another area where there is no set “right” or “wrong” answer - the viability of getting a correct yes/no result seems to vary on a lot of factors, and a big one is the particular deck and its personality/bond to the reader.
You’ve got some very interesting methods on the table, and I think the practice of backing up the answer with a second result is very clever! Thank you so much for adding these in, I’m grateful you shared them with us 
Thank you again to everyone for all your thoughts, methods, advice, and experiences - they have been very enlightening!
This space will remain open for anyone who’d like to continue to discuss tarot theory and explore the potential pros/cons of using tarot for yes/no readings. I’ve opened up a separate Part II for anyone who wants to do some hands-on experimentation with spreads and methods to get a yes/no result with tarot. It can be found here:
→ Using Tarot for Yes/No Questions PART II - Tarot Spreads for a Yes/No Answer
The methods and spreads kindly shared here have been collected over there for ease of access. Regardless of your stance on tarot, if you’re in an experimenting type of mood, head on over and consider giving a new method a try - perhaps with a different deck from what you usually use! There’s nothing to lose and always experience to gain
Blessed be, tarot readers
