First of all...
A big welcome to you, Mrs. L!!
Doesn't really make a difference to me....
I read with my cards set upright anyway, since I believe the card itself holds both upright and inverted/reversed meanings...
Also, when I shuffle...I know they get all mixed up...upright and reversed.
It's a matter of your style.
Sometimes, I put them all upright and in order and start a shuffle from there...but only once in a great while....
As I said, this is a matter of your preference.
If you do a search here you will find many threads discussing upright versus reversed cards in readings....
Here is our AT Table of Contents ....scroll down and there are many links on shuffling and on reversals:

As you develop your own reading style, you will do what feels right....
At the beginning of each sub-talk forum there is usually a "sticky" thread with some great information and tables of contents....
