I've only been soaping for a couple of months, so I try to order my FO's from websites that sell mainly to soapers. I look for FO's that have had a LOT of reviews and try to read most of them so that I know how it's going to behave. If there's an FO that just calls to me but hasn't had a lot of reviews...I try to plan a very simple soap and add the FO at the last possible minute. That way, if it does start acting up, I'm not rushed for time. I wish I could use the Scent Review Board but I only have the free email accounts and a work email, I don't think my company would be happy with me using my work email for soaping...lol
