Sir Ulrich, I want to mention, now that the "dust has settled" a bit and you got out to faire in the new maille and surcoat ... you took on the tailoring, it didn't come out exactly like you wanted it the first time, and you kept trying until you were happy with it.
The motivation to start on it, and keep working on it until you're happy with it even if it wasn't successful the first time - that is a key aspect of the do-it-yourself'ers. Keep that momentum and motivation for the chausses, horseman's slit and whatever else you want to work on with on your kit. Glad to see you stuck it out and pulled through!
