I used "Vanderspice". I bought several fragrance oils from a soap making supply company. I melt down the VDH and add whatever fragrance I am in the mood for. If I really like the fragrance I'll make 5 oz at a time. I don't think I'll make this size anymore though as it takes 5-6 months to use up. I use VDH because I like it better than the others I've tried. My wife is getting into soap making, so I'll probably make some from scratch after I learn which ingredients give the soap the properties I want. Sorry, this answer was way tooo long.....
