I'm sitting here with a Traditional Scottish hand-sewn kilt in the Stewart Hunting tartan. It's sewn to the sett, and is one of the nicest kilts I've ever seen. Unfortunately, it's not mine, but is here for another one of my alterations.

SOMETHING ELSE TO CONSIDER:

If you're using the tartan material that Chris at CheapKilts used, then you're going to be able to do whatever you like. IF you're using a nice wool material with the proper larger tartan, then you're options are VERY limited. The thin/smaller tartans do allow for some leaway in pleating, whereas the larger ones are so much nicer in appearance and authenticity!
