Spells are cast by constructing a spell box, which are enclosed altars or tableaux.
In general, a spell box is filled with power items necessary to achieve a goal, although you should follow directions given for specific spells.
It may be a cumulative spell done in increments: items are gathered one by one and added to enhance the power of the box.
Sometimes a special box lends itself to a magical or spiritual goal. The box itself can become an intrinsic part of the spell.
Attach and incorporate the power items to the box itself, such as charms, beads, shells and feathers.
Paint images on the outside or inside of the box to correspond with the spells goals.
Embellish with sigils or other symbols using magic ink, henna or other natural dyes.
