Hi, I'm an experienced knitter but have recently started making very different cobwebby scarves with a very open texture. My problem is that if the scarf is 10" x 40" on the needles, but when I cast off it suddenly loses shape completely and because the yarn is textured, it would spoil it by blocking. I have tried knitting a heavier section at each end but this has not worked either and I am left with a really shapeless "thing"! I am using 20mm needles and a very fine yarn for cobweb effect and I really don't want to add a fringe - maybe I'll have to? Any solutions/ideas gratefully received!
