First of all: I have an extra week. My mistake, my client is playing a week on friday, so I'm cool for now. Please, keep the ideas coming....

@Pleater: I think I get the idea. I'm not sure I want to go for your first suggestion. Good tips about raising the fabric edge though!

@Sydnie: I'm afraid I can't tell you who it was. Being in the trade, I know how easily things can go wrong when ordering online. Heaven forbid my clients start mailing me their measurements. Unfortunately, I wasn't there when he took the measurements.
Furthermore, I'm not the one having the issue, I'm just looking for advise. I feel it would be bad form to deride a colleague in somebody elses name. Besides that, I feel they may still come up with a solution today or tomorrow.

@Wiz......: Anxiously awaiting those pics! Oh, and eh... if a kilt is approximately 8 yards, does that mean the size is also approximately right?

In the end, I think my safest bet would be to take 1 4th off of each apron, and deepen each pleat adjacent by 1 4th. That should work, right?
