18th Century Dress - the sleeves

This being my first attempt at drafting a sleeve I followed the instructions in the book. But the instructions on how to turn the diagram below into a workable pattern was rather confusing.

So I used a little trial and error to make the basic pattern. Then I modified it to match one of the dleeve patterns in 'patterns of fashion'.

It wasn't possible to match exactly as I wanted ease in the sleevecap.

It looked ok when I pin fitted the paper pattern but I will need to try in fabric next.
