Thrift store Campbell Ancient kilt with moth holes

[Dale-of-Cedars]

Fortune favours the prepared mind; on my usual quick scan of the skirt aisle at Value Village I found a Scottish-made, hand-stitched, 7-yard, knife-pleated, medium-weight kilt in Campbell Ancient for $20, and it fits me exactly.

Of course the moth in the ointment is that it has a sprinkling of moth holes on the sides of the aprons and a couple in the pleats. [pictures will follow after the kilt spends the requisite 24+ hours in the deep-freeze.]

I saw the holes before I bought it and went ahead anyway, with the idea that it would serve as knocking-about kilt for around the house and for local walks.

The question I'm asking is whether I should stabilize the holes with a dark iron-on interfacing behind, or just not worry about the holes fraying, or... what?
Wouldn't reweaving a dozen holes probably cost as much as a new (casual) kilt?
