A jumper that can use scraps, temperature or mood themed or like me wanted to play with a full spectrum of colours from one range of yarn.
I chose Cygnet Pure Wool Superwash DK 50g and used all the colours available at the time. (There was a lot left over for another project in mind)
The body and sleeves were made flat, however the sleeves can be continuous if you are happy to apply the jog-less method.

I made mine fully flat and seamed the sleeves.
A knowledge of Kitchener stitch is a benefit but not essential.
The main body follows a a double row of colour in a flowing pattern to bring all the colours together.
