I have posted a copy of this pattern on my blog on the free patterns page at Parallax Knitting

This sweater has much to recommend it: it is warm and cosy and a fast enough knit to be ready before it gets too warm to need it. The cowl can be worn buttoned or open as an oversized collar. There is a minimum of actual direction in this pattern, with most sizing being placed anywhere along the row you like – like many things this pattern shows that random numbers can create great results.

Of course human beings do not make good random number generators as we dislike to see the same number appear consecutively, but for the purposes of this design that is fine, because humans are the beings who will look at your sweater most, and most other humans have the same biases as you.
