Because fly stitch is easy to do in a circle shape and next week we are studying the colour wheel at one of the groups that I belong to- I decided to interpret fly stitch as a colour wheel.
In the first sample I have used the primary colours -Red-Blue and Yellow.
I did one row of fly stitch around the outer circle giving it a long leg and added another inner circle with a shorter leg. The next sample has the secondary colours which are obtained by mixing the primary colours that are next to each other to get the secondary colours--i e red and blue make purple --blue and yellow make green and yellow and red make orange.
The last sample is the tertiary colours which are obtained by mixing one primary colour and one secondary colour together.
