You don't need items to do magick.
All you need is focus, will and belief. A bit of imagination helps too.
Words can help to focus our thoughts and intent and can be spoken, sung or thought.
Seeing what we want to produce in our minds, like a day dream.
Provoke the emotions inside of you as if your goal has already been met. For instance, if you desire a child (or you are casting for someone who wants to become pregnant) imagine the delight, feel it. Capture the moment and the feeling of the love of a mother to their infant.
When I do not use items, I practise magick in a trance. When I use items it is ceremonial, usually to honor or ask the aid of a specific spiritual being.
Stick with the ritual items of the religion practiced in your area. Most have altars with candles, so as long as you don't stray from the "normal" religious items of your location, you should be able to use them without any trouble under the guise of that religious practice.
