I knew I wanted to make something that followed the reed-like pattern of Knitting Nature, but with no book and thus no pattern I had to wing it a bit.
I cast on as much as I could fit on my brand new shiny metal needles (the only kind sold in Argentina) in a size 5 mm, which came out to be 140 stiches across, or if you prefer 35 sets of 4. 4 stitches purled, 4 stockinette, 22 rows of this constant ribbing and then 4 rows of all stockinette until you switch, checkerboard style, and start over with your purl and stockinette pattern.
I have no idea if this is remotely close to the original book pattern, but it seems to be working out, if you like woolly sausages-which is what my poor blanket strongly resembles. But it is very warm and with a bit of blocking I think I may be able to make them less sausage, more reed, which is the goal.
