Good morning world
As someone who hasn't ever made a candle, but has overseen many a spilled hot wax cleanup, I can also suggest putting a brown paper bag (or newspaper if the rug isn't some light color) over the wax in the carpet and then using a warm iron to melt the wax so it will stick to the bag.
Wishing everyone a 'damn, that was easy to get out' kind of day.
