Here is the first Armstrong's blanket: the vintage granny square. The colour combinations are truly shocking, but it has been made well, in complete squares with each square finished off before the other one began, and all of the ends sewn in. Here is a close up showing the colour in its full glory.
And here is the vintage granny spiral. Not a square after all. The person who made this was not that skilled: they just crocheted round and round till they ran out of wool or felt like changing colour. The ends are not joined but knotted and cut (aaarggh!) but it is a nice looking blanket anyway and it hasn't fallen apart yet so I'm sure it will be fine.
There is a lot of green and grey in this blanket, but that is accidentally exactly what I need for where it is going to go.
Here it is hanging on the line outside in the snow. You can see the large green square. I suspect whoever made it thought that they would make a plain green and grey blanket and was surprised that they ran out of wool so quickly. These blankets do take a lot of wool.
