Ted,
You have the opposite problem from me; I have to lengthen my sleeves! I have 3 thrift shop jackets I'm planning to convert to Argylls, and so far I've been able to steal 1 1/4" from the cuffs.

VMac,
I plan to make my gauntlet cuffs from the fabric I cut off the tails of my jackets. If you lay the cuff piece flat, does it look like a valley or a peak? I'm thinking it should be a valley, with the "peaks" stitched together on the back of the sleeve. And, what are the measurements of the peaks and valley? From the pictures I've seen, it looks to be about 3" sloping up to about 5". Like Ted said before, it's hard to put questions like this into words, but I think I've explained it. Your help will make it easier for both of us to convert our jackets. Thanks!
