Grizzled Ian,

Sorry for the delay in responding here. Yes, 28" is more than wide enough to make you a 24.5" long kilt. It's a traditional suck selvage, woven by D. C. Dalgliesh. For more info, I suggest emailing me at matt@newhousehighland.com

I have one other person interested in a kilt. Depending on the style of kilts wanted, I may have enough to satisfy you both, we just need to work out the details.
Aye,
Matt
