This is 'Collar' from Sarah Hatton Knits '10 Simple Crochet Projects' - a gorgeous booklet with its matt pages, beautiful photographs and simple projects. So many more that I plan to make. I shall add them to the list.
The pattern suggests, and I actually did use, Rowan Softknit Cotton, purchased from John Lewis. This is the colour seaweed and it is such a gorgeous cotton to work with - soft, drapey and squishy. I made the longer version, sewed on a button from Great Gran's tin and proceeded to wear it lots. I do already have the wool for the shorter version, so you may see that soon!
