I would suggest you to read some books on basics to know how spell works,
Some books are:
"Before You Cast A Spell" by Aleister Crowley,
"Menace of Spiritualism" by Elliot odonnell,
"Modern Magic" by Donald Michael Kraig,
"A Practical Guide to Witchcraft and Magic Spells" By Cassandra Eason.
Have an exceptional amount of knowledge before-hand and know what it is you're trying to cast. get an assortment of different colors of candles from somewhere and be sure your materials are in order. Message me if you have specific questions, I'm also a new poster here.
