Anyone else make soap?

We've been having problems with some of our soap molds releasing and was  wondering if anyone else has had this problem and overcome it and if so, how.

Yes, I am a soaper. 

If you have a problem getting the mold to let go just pop the whole thing into the freezer for a bit.  It won't affect the soap at all.  When you take the mold back out the soap will have contracted slightly from being cold and a very thin layer of condensation will form between the cold soap and the mold making the soap slip out a treat.

Of course then you need to let the soap thaw out a bit before cutting.  Frozen soap is hard. 

Thanks.  I'll try that the next time because I really like the molds, but it's ruining the looks of the soap.  I made some lavander soap and put some of the petals in it, but it stuck in the molds.  They would have been pretty if I could have gotten them out.

Could you maybe spray the molds with cooking oil?
