I've crocheted a Lorenz manifold (google for chaos and
crochet and you'll find Hinke Osinga's pattern), and I have put in two
out of three axes. Alas, the hard part will to put in the third...
The manifold up to the last blue row
before the last one. It is a nice lap-blanket now. With all that folds
it would even work for a highly pregnant women to warm her belly...
I might have to buy even one more ball of yarn of red and bordeaux. Using less colours makes it less yarn-intensive.
