La Cotte Simple – Excellent blog by renowned independent scholar of Medieval clothing, Tasha Kelly. She provides provides tutorials, articles and all kinds of useful information from her experience. You want to be listening to her! She is also the author of the Charles de Blois pattern that I used to create my personal arming doublet.
Fuhlen Designs – Jessica Finley is another very gifted medieval tailor who shares her insights and amazing work through her blog. She had the opportunity to study the extant Lubeck Jack and create a fantastic reproduction of this surviving martial garment. Jess is also a very accomplished HEMA practitioner and armored fighter.
Will’s Commonplace Book – Blog of the late Will McClean. Will (many in the SCA will know him as Galleron) has probably contributed more to the community than most anyone else. Sadly Will passed away in the Fall of 2015, but he has left behind a legacy of shared research and insights into the Middle Ages that I encourage any student to read.
Katafalk – Cathrin Åhlén’s blog. She is a classically trained tailor and provides a lot of good information about historical clothing and tailoring. Not exclusively medieval, there’s still a lot to be learned here, check out her tutorial section as well!
Schola Gladiatoria – Matt Easton of Schola Gladiatoria in the UK brings to the table more content on historical weapons (main focus on swords) than any other channel on YouTube, hands down. If you have even a passing interest in antique and historical swords, Matt’s your man.
Metatron – Raffaello Urbani’s excellent YouTube channel covering a wide range of historical topics from Ancient Rome through to Medieval Europe. Raffaello is also a gifted polyglot and produces very interesting linguistic content as well as topics on gaming as they relate to history.
LindyBeige – Most historically minded YouTube watchers are probably already familiar with Lloyd of LindyBeige, but if not please check out his channel as well. His historical program debunks and his “A point about…” types of videos are of particular note.
Shadiversity – YouTube channel by Shad Brooks. A small but highly content-rich YouTube channel that covers a lot of good information about swords, philosophy and gaming. Shad provides some unique insights not found elsewhere on the web.
Thegn Thrand – Thrand and Eldgrimmr team up on this YouTube channel to apply experimental archaeology in an attempt to debunk a lot of the really bad myths out there about armor and weapons. They’re not afraid to get their hands dirty!
