Framing, What? (Pt 1 )
We are a little confused about framing. Let's talk it out.

1) TAKE IT TO THE PROS
The EASIEST way to frame is to take it to someone who knows what's up with framing. They will make sure your art is safe and sound for generations to come. They will have good ideas and wise advice. However, they are paid for that wisdom. This option is the easiest, but it is the most $$$
If your art piece is a standard frame size it might not be that expensive. But as soon as you dip into custom frames the price goes way up.
My favorite (PNW local) framers are Museum Quality Framing. They are super smart. They also have some more affordable options I've taken advantage of. My advice when going to the pros: ask lots of questions and don't be afraid to ask about cheaper options. They want to help you.
2) DIY
You can make your own frame and cut your own matt. You can do it! But it's labor intensive. It's a life style choice. You can also make your own frame and then get someone else to cut you a custom mat. HERE's a helpful video on it (she doesn't have the ideal everything which I think is relatable and helpful). If your art work is on a wood panel or canvas you'll need a floating frame. See HERE on how to make a floating frame.
