Just bought Nancy Z's book " Confidence in fitting patterns". It features her pivot technique for making adjustments in patterns. Haven't tried it yet but it does make sense. I still want to get away from relying on manufactured patterns and have the ability to draft and design my own blocks or patterns.
I think the answer is to use a little of all ideas to come up with something you want to make. For a man that has some weight to him expects to have a good selection of patterns to choose from, he will be on the hunt for a long time. I prefer to have more control over my hobby.
