This is what I managed to do with the leftover yarn.
I started another bit to actually make something but I've pulled it apart as I didn't like how loose some of the stiches were compared to others.
So thank you Lindsay! I'm now able to add yarn to my craft supplies hoarding!!!!!
I'm planning on trying to make a scarf or two for my lot. We shall see how it goes. FWIW my DH is thrilled, which I find shocking, but I think it is because it is something his mum does.
