Crocheted squares are often called «granny squares». Probably because they often are used in blankets, worked by granny or somebody like her. To make one, you will have to crochet a great number of squares in a lot of different colours and put it all together. It is a very smart solution if you have too much left over of yarn. And most “crafting people” have.

It was not really the granny squares which were the inspiration for the vest Squares, but some small coasters to put on the coffee table. Still, to put something like that together in a larger piece, will very soon bring one’s thoughts to granny. That is why it is exciting to make something that is similar, but still is very different, both in expression and shape.
