You can devise your own spread. Anything that you feel comfortable with is fine. After all, you are working with the cards and universal energies and can decide if you prefer one of your own spreads over the traditional ones.
For instance, you may just want to draw one card for a particular issue. Or you may wish to draw 6 cards, or 12, representing the months of the year and how they will go. You may wish to only draw four cards one for each season or 12 in 4 rows of 3. Whatever you choose is fine. Just be consistent.
