I’ve recently been reading the blog Tea in a Teacup by an Australian woman who likes to recreate historical costumes.
I was drawn to it initially because she has an attractive legible and more importantly pink WordPress layout. She discusses in relevant detail the patterns and decisions she makes behind the garments shown on the blog and also gives her own self-criticism of the finished product, suggesting how it might have been done better or acknowledging something that was not period appropriate. She shows step by step photos and details the patterns she uses.
I think it works well because she provides reference photos and links to extant garments, and also not only encourages conversation on her posts but responds to her commenters. She provides a link to her Facebook page and from there Facebook displays ‘pages like this’ so her readers have the opportunity to visit other similar blogs and sites on the same sort of topic.
