Put the crushed rose petals into soap molds so that they cover the bottom of the cavities.
Cut soap base into 1 inch pieces and place in measuring jug.
Microwave for 30 seconds. Stir very well. If not completely melted, repeat at 10 second intervals until fully melted, stirring in between.
Add essential oil and stir well.
Add few drops of pink soap colouring and mix in.
Pour mixture slowly into the soap moulds.
Lightly spray with rubbing alcohol to prevent bubbles from forming on the soap.
Let set for about 60 minutes in a room temperature.
Carefully remove from mould and wrap or use straightaway.
