This shawl is amazing !!!
I tried to change the overall shape by adding 2 stitches instead of 1 on both edges and it was a success. Had to be extra careful with the pattern, I used paper and pencil to get everything right. It turned out a triangle with the sides longer than expected, and I like it this way.
It is white and quite heavy (about 400g), and wearing it I feel like Jane Austen or one of her heroines, so old-fashioned and stylish !!!
