Yoga Props: Are They Necessary?

Yoga Strap Around My Arms

There are many different Yoga props out there, but are they all necessary? When I found Yoga, I practiced with no props, and I still often forget about props and teach without any regard to them. Some Yogis say you have to have props to do Yoga properly, and others, like myself, realize that there are many things around the house that can be used in the same way.
