A Bit of Nalbinding, and a Status

I have done nothing relating to costuming this month.  Mostly that's because I've undertaken a temporary job, working for the US Census Bureau.  It has left me with zero time and energy to do anything extra.

But I did find a video that mentions an insole with nalbinding on it.  The video is by the Medeltidmuseet in Stockholm, and as you might expect, it is in Swedish.  However, it gives a look at a leather sole with a bit of nalbinding along one edge.  This find is dated to 1300-1400 CE.  The link can be found on the Nalbound blog, here, which is in English and gives a bit of perspective on the find.  (Kudos to Anne Marie Decker, who writes the Nalbound blog.)

Was this bit of nalbinding part of an insole?  Or is this evidence of a nalbinded sock with a leather sole attached?  The blogger at the Nalbound blog thinks it's an insole because the "row [of nalbinding] appears to follow the edge of the leather sole. That direction under and along the arch does not match the row direction that I see in contemporaneous nalbound socks."  It's an interesting look into a different way that nalbinding might have been used during the medieval period.
