I agree with Paul, given the thickness and softness of the Harris Tweed cloth, I would not want to use much more than 5 or 6 yards myself. This Harris tweed kilt I made uses about 5m of cloth, and it is as heavy as I would want a kilt to be. Any more and I believe it would have been overkill!


Having made and worn both kilts from Harris Tweed and typical worsted wool tartan, here are my observations on the differences.
1. Don't expect as crisp or flat a pleat with the tweed kilt. Be happy with a softer, more rolling pleat.
2. Because of the thickness and softness of the fabric, a tweed kilt will feel warmer and bulkier than a comparable worsted wool kilt (made from the same weight and length of fabric).
3. A tweed kilt will definitely have a more "country" look to it. I love wearing tweed kilts for daywear, but I don't think them especially suited for formal occasions.

I cannot say I have noticed any difference in "durability."
