After about 26 hours the soap seemed ready to cut...here it is in "bars". It won't win any glamour awards that's for sure... :*)
Now it just needs to cure for a few months. One thing I have learnt from this exercise is to make sure I oil any plastic trays I use in future! I think the milk carton mould works the best so might just go with that.
It now smells more "soapy" than "olive oily" which is good - and the oatmeal / rolled oats make it look a bit like a slice rather than soap.
