the simplest spread is the 3 card spread called the past, present and future spread. or its called problem, suggestion, answer spread.
another favourite of mine is the seven spheres of life. they are love, work, money, family, health, travel and home. of course you dont have to follow them exactly.
theres also the celtic cross. it is a ten card spread. google it and see the layout.
theres also the 13 card spread for the year ahead, also called the calendar spread or the horoscope spread. 12 cards in a circle with a thirteenth in the middle. it represents the twelve months of the year and the middle one is a overall card for the year. the thirteenth is optional of course. just start at the current month
theres the 21 card spread. called the gypsy spread or the romany spread. three rows of seven cards presenting past, present and future.
some of the bigger spreads require more energy and concentration so its prob best to start out with small spreads and work your way up.
