Here is the 2ND part in my huge wall hanging and it's crocheted up quicker than I have cut the fabric.
On a 20 mm hook no problem and it's my favourite wooden one. So easy once you get going, and I'm using a different technique than usual. I would go into each box when making a fast knit but this time I am going into each top loop of the stitch. Accidental discovery when making the orange scarf but I like the way it raises the stitch.
