Update:
Almost done! Having an issue with "Tapering the Fell". It seems my rump and where the kilt will sit are the same measurements. Just to be sure I will have my wife measure me when she gets home (should be soon). However, if they are the same measurements, then what?

I originally was going to do a knife pleat but went ahead and did the box pleat of the xkilt. So far it's looking good and can't wait to put it on.

For those wanting to make your own kilt, be sure you are willing to put in the TIME and EFFORT because its a lot of time and a lot of effort and things will go wrong if you are new to sewing. Keep at it.
