Here is River completed (as in knitted). It hasn't yet been blocked and there is still the beaded knot to knit.
I have never knitted anything quite as fine and delicate as this before so will have to read up to try to ascertain whether or not it should be blocked in any particular way. This was literally like knitting with gossamer. Is this similar to what is referred to as cobweb lace? Then again, this is all relative. Imagine how fine the Wedding Ring Shawl must be. I have read that it's name derives from the fact that it is so fine that it can be passed through a wedding ring!
