Daryl Lancaster teaches several classes geared towards handweavers. My weaving guild brought Daryl to Utah to teach 2 classes.
This is a 3-day class. The Daryl jacket is a cardigan style with a band around the neckline. One version has a higher sleeve cap and armhole and a dart on all sizes. The other has a lower sleeve cap and armhole with a dart on some sizes.
The first day started with some basic fit information. Daryl has her own jacket pattern and samples of each size. Each person tried on jackets to get the best fit in the shoulder area. Daryl picked the sizes to try but left the decision of which to start with to us. The patterns sizes are things like A red, C purple so there is no clear 'this is how big you are'.
After the starting size was picked, Daryl looked at the fit and listed the alterations each person needed. She involved the class which helped us learn what to look for and how to fix things.
After a discussion on alterations, we tracked our pattern making the alterations Daryl had written down. This was really clear in the instructions and the list of alterations.
We had homework to cut out our jackets that night. The next morning we talked about some 'how tos' and then started sewing our jackets. It was so fun to see other's jackets taking shape. Throughout the next 2 days we sewed, tried on, and asked questions. When we needed to unpick, Daryl told us to bring it to her. One person completed her jacket, most of us got far enough to know the jacket fits well some had just hems to sew to finish their jackets.
This was a great class. Even the most knowledgeable people in the class learned things and those without much sewing experience had jackets close to complete at the end.
