As luck would have it, I now own a fairly light wool kilt which is several inches too long for me. What are my options for changing the length?

Ideally, the kilt will be selvedged instead of hemmed. But now I understand that selvedging is done by the weaver, not the tailor.

Is there any way to "re-selvedge" wool?

Are there any other options, apart from hemming? Will the kilt need to be completely re-tailored?
