I've just found this wonderful resource:
It's all about vintage patterns and sewing using vintage patterns. But what I really like is that it can be used to produce contemporary garments too. I was very impressed with the detail about how to make a calico pattern and how to adapt it by altering dart positions and how to make tucks etc. I've not done this for over 30 years, so it's wonderful to be reminded of how to do it. It's certainly a site I'll be going back to!
