The Rainbowgan cardigan knitting pattern from The Drunk Knitter makes a rainbow for the yoke from a single skein (or two) of yarn. Before knitting you divide up the colors so you have long runs of a sing color rather than alternating among them throughout the garment.
Of course you can just knit the yarn as it comes to you and you’ll still have a really pretty sweater.
The design comes in eight sizes to fit a chest measurement from 30 to 62 inches with 0 to 4 inches of positive ease.
You can get the pattern at The Drunk Knitter.
