Your Wardrobe Unlock'd / Foundations Revealed

I've subscribed to one or both of Your Wardrobe Unlock'd and Foundations Revealed for a while now. They each publish an article per week; generally they are tutorials on how to make a specific garment or detail, draft a pattern, or approach some aspect of sewing as a business. What they offer is unique, so I was sorry to learn that they're having trouble getting enough subscribers and might not be able to continue.

YWO focuses on historic clothing (medieval to early 20th century, so far) and FR on underclothing (mainly historic but also modern). Yes, they are rather specialized, but do have a look if you're interested; some of the articles are accessible to non-subscribers, to give you an idea of what they do. They're discounting the subscription price for the first month.
