Dragon's Blood, Egyptian Dragon and a blend of the two make a nice earthy. Hardwood Musk for California Candle Supply is a really versatile earthy, musky that can be mixed with citrus, florals etc. It is another one of my duped fo's. Vetiver EO is quite smokey and only needs to be used in small amounts. very small amounts, I have never tried but one, vetiver fo and it did not smell like the eo in my opinion. Big Sur from Soapalooza is another great fo that mixes well, to me it smells just like walking through a forest on a damp morning.
