Haven't blocked it as I think it's going to be ok as is. Worked the single crochet all way round the edge adding another row on front where the zipper is. Also put crochet tabs on the collar for button closure.
I expect my DH will be wearing it before it gets a wash.... he was wearing the last one before I got the buttons for it.
I think it would have been great with a fleece lining but he said that he didn't want that.
