To achieve the best result I would recommend you to use Pipettes. If you don't have time, just use 1 colour of your choice and decorate ready soap with mica.
In the photo, I used Soap Colourants by Eternity Lime and Mandarin.
Dimensions of the ready soap:
- Height: 5 cm
- Diameter: 6.5 cm
- Weight: 26 g
