I have a template for the shape of N's hand, and it seems to be just the same size as mine. So I cut and pinned a calico toile on myself - fingers too long, thumb hole too deep, and the wrist seems very tight. I made a pair for my DH, so asked him about his - they are also a bit tight on the wrist, so it is clearly a fault of the pattern, and I have marked it as needing more width.
The chamois is very stretchy, so they may well be too loose, but I can always tighten them up a bit. No hanging about on this job - need to be posted in a couple of days.
