I have numerous kilts. Several were my MIL's, a couple are my DH's from when he was in a drum & bagpipe band and I have a few of my own.
Given that the wool is probably valuable, and it's a true art to actually make a kilt (believe me, I learned that lesson from my Scottish granny-in-law when I tried to make a kilt for my wedding) I want to declutter them properly and with respect.
Do I give them away? Try to sell them? I'm almost thinking of wearing mine again in the winter, but maybe that's just dreaming. They are supremely practical and warm. With leggings, boots and a nice wool sweater by the fire--ahh!
