I realized as I was working on documenting my HSF UFO project, that the write up is already getting long and I should probably break it out into parts. I don't want to give away what I'm working on (other than it's 18th century!) so the drafting of the sleeve seems like a good part to piece out. (Hehe, piece out...)
Anyway, to start on creating my own sleeve I always make a line dead in the center of the muslin. From there, I measure out half my wrist measurement and my underarm measurement on either side of the line. It ends up looking like the orange lines on this piece of muslin:
But I don't want a generic elbow length sleeve. I want a reasonable approximation of an 18th Century sleeve. Most of the 18th Century sleeves that I was looking at have the top of the sleeve towards one side rather than in the middle as I do. This means moving the underarm part of the sleeve to one side.
