Do you read cards almost instantly? Or do you have to sit and read the cards for a few moments until something/feelings come to you?

 

Both.
There's an instant, instinctive impression from looking at the cards laid out. After that, I look at the way they interact with each other. Sometimes that part requires a bit of reflection.

Sometimes I "get it" at once; other times it can take days. There's not really one answer to this...

It depends. Sometimes a reading will be really "in my face" and I'll get it instantly. Other times, I have to sit with the cards for quite a while before grasping what they are saying. Usually, though, the reading will give me a general impression instantly - it's the details that sometimes take a while to become clearer.

I sometimes get an immediate gut feeling when I see the whole spread, other times I have to do a full analysis of the spread to understand the reading.  It really depends.
