The items needed for a Full Moon Love Binding include:

A red or pink candle
A single red candle (separate from the first one above)
Red or blue thread – one long string
poppets, representing both you and your heart’s desire
Poppet: a handmade representation of the parties involved in a spell, usually the target of the spell casting. In the case of the Full Moon Love Binding, wax poppets of both partners are needed and should be created out of the red or pink candle mentioned in the first bullet above. Create a poppet out of a candle by melting the candle and shaping it into a poppet once it’s soft enough to be molded. More on candle colors and their significance can be found in this article’s FAQ section.
