I did this class on Sunday and it was brilliant! We used a drafting method by Anastasia Vouyouska and drafted straight onto calico so that we could cut out and sew up to fit. As soon as I got home I just cut around my drafting lines and traced my block onto paper.
Alice was brilliant. She explained how to draft with this method, fitted everyone's toiles and then went through how to make design adjustments to the block using mini pattern pieces, scissors and pencils so we had lots of bit to take home!
She had the Anastasia Vouyouska books and stencils for sale, which I am thinking about buying. Everyone in the class (5 of us) had very well fitting toiles at the end, so I think that's a good indication that it works! I am not sure how well I would do just following the written instructions without a teacher to guide me through it though.
