Deutsch im Stricktagebuch vom 1. September 2013.

I wanted to emphasize the angular look of the shrug and designed the color fields in a sort of graffiti optic.

To obtain shape and patterning you have to work shortrows, increases and decreases in the round at the same time. This is free-short-rowing, which requires no pattern but skills in a technique. If you want to learn it go to Heidrun’s Ravelry Swing-Knitting-Site where you can buy tutorials to learn and exercise and watch her site for live courses.
There is a distinction between free short-row-knitting and “guided” short-row-knitting. The tutorials will at first teach you to knit “guided” short rows which have calculated stanzas to avoid frustrating beginners.

Free short-rowing as worked here has its own rules. You don’t need a pattern because its on your own to create and calculate your project. My notes above are enough to enable every skilled short-row knitter to do the same. There is no need to write a pattern.
You cannot know how your project will look in row 68 i.e., but there are rules to know what to do in the special situation in row 68.
A pattern for free short-rowing is theoretically possible but practically would have 100 or more pages, because every single row doesn’t look like the one before and every segment is different from each other. You won’t pay for it, I bet!
Advanced knitters of free swing-knitting techniques only need a few details to knit a similar project.

The different color fields are knit in a special algorithm. That means: the short rows are shortened in various intervals. Those intervals are combined in a numerical order. This order is determined by yourself before starting to knit and will never change until you finish your project. This will result in harmonic forms.

For knitting a project like this you should have advanced skills in shortrow-knitting as in free swing-knitting. Sorry, it’s definitely not a beginner’s project.
