If you want to enchant an item; first think of what you want its abilities to be. Such as: a protection ring; an elemental wand etc. As for the protection ring, hold it in you hands, like you were creating an energy ball.
Visualize energy everywhere, and draw it to your ring so that there's energy in it. Now you've got, let's say: a special connection, with the ring. Now believe in its abilities and its enchanted, because it isn't as hard as you might have thought.
