It pays to scour the web for inspiration.
I was going to write my own pattern for a hat like this granny st hat, but I came across a free one that was easy to read and to make up.
The hat is for a child.
But I was planning a different look, so here are my changes.
The hat is made as per the pattern, I made up a granny square of 3 rounds and placed the square in a triangular position onto the hat for an ear flap.
I placed 2 corners on the very edge of the hat edge and sewed them into position.
I made sure they were placed apart to fit correctly over the ears.
For the ties with 2 strands of yarn held together, I chained 50, then made a mini cork screw on one end.
I also did a row of sc around the hat before I sewed on the ties.
And here is the result, simple yet effective.
I used 8 ply yarn and a 4.00 mm hook.
Here is a tutorial for the corkscrew.
