Don't give up just yet, everyone has to start somewhere. Keep practising & before long you'll be making fine candles. Sounds like you needed to do a repour on the sunken top candle. As the top of the wax is setting up you need to make holes in it, I use a skewer & wiggle it about gently to make the holes a little bigger, then pour in some more of your wax at a temp. a little higher than the setting wax, til its level with the original level of your candle. You may need to do this more than once.....that is if you're making pillar candles. If you're making containers a single repour is usually enough, though the waxes I use don't usually need any repour in containers.
