work out what it cost to make, card, ribbon, tea light etc.
i'd say for a craft fair i'd try to keep it under £5, that way your more likely to sell them, and if you can offer an extra candle with it.
you could try selling 2 at a time in an offer, maybe 2 for £7. give a few options if you can to give ppl an incentive to buy.

HTH,
