I wasn't much into the granny square back in the 70's. Especially those vest. There are so many variations for the granny now and they are so simplistic to make that I am on a mission to create as much as I can from a granny square. I guess the vest has made it's way back, but I still cringe when I see them.

Here is how I remember them. Guess they would be cute with a pair of shorts and as a crop top. I still do not want to attempt one of these, but all the other Granny variables, here I come.
