6% is plenty if you use good oil. My 2 3\4" candles could scent a 500 sq ft space with 4630 and 6% FO. 10% will drown your wick or make a huge flame. If you want a candle recipe use a small jelly canning jar, 4630, HTP 52, 6% FO and use a light FO. Cannot tell you which fo since I used to use Peaks but their cranberry worked and the Christmas Spruce did too. Bakery scents are hard to wick. You may be pushing it by trying to get this right for Christmas this year. Good luck.
