Discolouring Fragrance Challenge
This month was a discolouring fragrance challenge run by GalaxyMLP, the basic rules of the challenge were to use a fragrance that discolours and incorporate that into your soap design. You also had to choose a colour scheme for a famous brand or sports team and incorporate that into your design too.
Below is the original challenge thread if you would like to read the full challenge criteria and see people's discussion of their experiences of the challenge

And here is my entry.
I chose to use Wimbledon as my theme as I love the combination of purple, green and white.
I used a basic slow moving recipe at a 5% superfat of -
25% Palm
25% Coconut
25% Sunflower
25% Olive
The discolouring fragrance I used was porridge oats from gracefruit which I used at 3%. The description says it discolours to a dark tan.
I wanted to try a sort of different butterfly swirl with this challenge. I tilted the mould slightly to one side, then filled it with 1/4 of the discoloured batter, then I alternately poured the white purple and green until the mould was half full. I then used a hanger in a circular motion to create the bottom half of the butterfly. Then I poured in some more discoloured batter and drop swirled the colours in on top to create the top wing of the butterfly.
Here is the soap when it was first cut
