I've just bought my "almost perfect" v neck knit. The only problem is that the cuffs on the sleeves are very loose ie they have been knitted intentionally wide. Is it possible to gather them in some way so that they are a little more fitted? I was thinking possibly shirring elastic sewn through the rib? If it makes a difference, it's cashmere. I'm not expecting to make them tight but rather adjust them to something a little less flappy!
