Are you looking for this years Festive ones or previous?
I like "Cosy By The Fire" this year but it's not as nice IMO as "Sparkling Cinnamon"
CBTF is cinnamon/clove/orange
SC is cinnamon/clove
I love "Spiced Orange" it's a bit like Pears Soap
DD loves "Candy Cane Lane" - vanilla hint in mint
"Christmas Cookie" - smells much nicer burnng than in the jar
"Salted Caramel" - gorgeous , not overly sweet like you'd imagine
I don't like pine or the Gingerbread ones
The large jars have a 150 hour burn time but make sure your recipient trims the wick to 1cm long and burns it for at least 3 hours till the wax melts across the top, otherwise it tunnels.
You could buy them some votives and a votive holder (they melt to liquid so they need a holder)
or Tealights
Then you could get a selection of smells.
I love Yankee Candles.
I have a 20% off White Company but was underwhelmed at their winter candle and the 20% off didn't even tempt me.
I'm going to buy a Sparkling Cinnamon Reed diffuser for the loo.
