Hello Candelosa and welcome to Aeclectic!
I have the Old Path and love it - and I am not a Pagan either. I find it very easy to read with - it has a gentle but strong voice all of its own, very natural. Its use of flower and other plant symbolism is particularly interesting. Its roots are in earth spirituality, but I don't think you have to be a follower of the old path to appreciate and read with it
Huredriel on this forum started learning tarot with the Old Path, and swears by it. It's by no means a difficult deck, though like all Tarot, it takes practice and patience.
Here is the study group for it, if you want to read more about it:
