”Riverrun is the former seat of House Tully, who continue to hold it in defiance of the Iron Throne and its new lawful rulers, House Frey. It is a large castle located in the central-western part of the Riverlands. It sits at the point where the Red Fork of the Trident River is joined by its major tributary, the Tumblestone River flowing out of the west.”

This is a shawl knitted in garter stitch with a lace border. It’s a halfcircle shawl with extra increases in the end to make the shawl a bit more crescent shaped, note that about 2/3 of your yarn will be used for the edge. Together with the lace droplet motifs and the BO in waves this is Riverrun.
