LOOK at the SELVEDGE!!!

[Woodsheal]

AND, for the LIFE of me, it LOOKS like they have a binding around the ENTIRE perimeter of the belted plaid (look at the bottom and top edges, as well as where the material SHOULD have the cut edge hem).
Interesting.

I've read descriptions of wool or silk tape binding around the edges of plaids from that period. Some of my reenactor friends do this to theirs, and it looks good!
