start out by chain 3 and join. work in rounds, increasing for first 2 rnds, then work even. then dec evenly for next 2 rnds, gather stitches and close opening. evenly space where to put the octopuss legs, there should be 8 of them. i'd chain up to 10 sts and then slst back to the start, move over one spot and make another leg til 8 are done.
you can make a black chain eye in the head section.
