I must admit that until recently when I started to make larger quantities of soap I used to just toss all the odds and ends away. Now that the quantity of the leftovers is increasing it just does not feel good to throw away such a large amount of soap. So I cut the soap in pieces, some larger, some smaller.
Then I put them all into a pot together, add some water and put the pot into an oven heated to approximately 90 C. When about half of the soap cuttings have melted I stuff it into a mould.
And here is the result: My exclusive "Limited Edition" Tutti Frutti soap :-D
