Bottlecap offering tealights made with leftover wax from another candle. I ordered anchored wicks and then dumped the wax in.
So far so good! I don’t know how long it will burn, but one’s going right now for Eostre, so I can let you know!
Edited to add: It lasted between 35 and 45 minutes (soy wax, don’t know if that makes a difference). I say this is a win for using up leftovers if you can find affordable wicks!
