Crochet: Granny Square

My long neglected Granny Square crochet has been behind my efforts.  I think they have paid off because this morning I was emboldened to try a new square.

It isn't perfect but it is essentially right.  I thought my problem was that I couldn't turn corners.

In fact the problems were legion.

I could not read the patterns.

I did not actually understand double crochet from single crochet or a hole in the wall.

I wasn't holding the hook effectively.

My tension on the hook and yarn was really TENSE.

Ten year old or so square on the bottom, today's effort on the top.  Not stopping till I complete this.  Go me!
