So how is a poppet different from a voodoo doll? Seems to me they're the same.
Anthropologists use "voodoo doll" as a generic term for "poppet" in their books in any cultural context, e.g. for figurines pierced with nails according to Greek Magical Papyri formulas where of course no African-Caribbean was involved (surprisingly unscholarly of them to align their terminology with popular Hollywood-influenced culture).
Some authors writing in favor of cursing opine that curses help restore peace of mind in the caster - the ritual is done, the problem taken care of, let's move on to more productive things. You won't get that peace of mind if you keep repeating the ritual over and over again, it will just rekindle the hate, the anger, whatever, and ultimately become an obsession, and a very unpleasant one at that (unless you're of a sadistic bent and look for a pretext to curse people right and left).
I agree with
@Ancient - this is not a type of operation that lends itself easily to routine daily repetition, not like Damon Brand's "Success Magick", for example, which takes a staggering 49 weeks to complete but is basically work on yourself. A curse should be involve a climactic ritual, I feel, and not be repeated by rote every day.
And only ever ask questions here if you are really sure that your ritual was unsuccessful, otherwise you'll talk a spell that is still pending to death.
