My friend gave me about 2 pounds of rose hips. I would like to scent these but not sure what type of oil to use. I went to NG to order oil and the shipping is high, so I called Lone Star ( which is close to me) and they told me not to use candle oil because of the flash points. How much oil do I need to scent 2 lbs. Can anyone tell me how you do htese? Thanks,
