‘Crochet again’ has now published version 3.1 of her super Granny rectangle pattern, and this one has only a single line of the base colour (here). As soon as I saw it the word ‘scarf’ slipped into my mind and here, without further ado, is what I came up with:
It is in the same colurs as my ‘Down to Earth’ blanket (here) but you will notice that the starting rectangle is different, so the first colour ends up as the same width as the other rounds.
I had a starting chain of 34 motifs which was 74cm long, and ended up with a scarf which is 110 x 36cm after 18 rounds. The same starting chain would have given a 96 x 28cm scarf if I had stopped after 14 rounds.
