I am not usually one for burning candles - i find them very cloying and they give me headaches.
I tried TANDA Moderns candles - i love the Oak moss and amber - and have found the scent subtle. It does not give me a headache at all. I burn my candle or melts every night. I have tried a number of other scents and find the same thing. Very clean burning and the scent is long lasting but not over powering.
I think everyone that loves candles should try TANDA Moderns range!
I have found the service to be brilliant. I call my order through and they are usually ready the next day for me to collect.
Also Alyson - the founder and owner - is happy to take scent suggestions as well.
