I am very new to this but last Sunday I did a melt and pour. Glycerine base, red colour, rose petals and patchouli scent. Being cautious I melted a small block of base and added dried rose petals, red colour and the FO. I didn't use enough base maybe I should have added water or milk as it didn't fill the mould but once it cooled I had a perfectly formed round soap okay it was about a quarter of an inch thick but it looked good, red and translucent so when I held it up to the light I could see the petals in it. It also smelt nice maybe a little weak on the scent and when I used it, it lathered beautifully and felt lovely and soft but.... The colour stained my hands What did I do wrong?
