I bought 4 meters of St. David's tartan from martin Mills. Double width and cut it in half. thought that would be enough material.

As I went to knife pleat it to the sett last night with deep 3" pleats I am out of room for my inner apron by about 14 inches so not enough material.

there's probably 3 ways I could go here to make this work.

1) I could pleat less deep 1.5in, but don't want it to look strange.

2) or scrap the knife pleat and go with the box pleat style. I've never owned a box pleat kilt before but it doesn't look too bad to me

3) I could keep it the way I have it but sew it onto another piece of material (from my extra material) to complete the 21 inches for the inner apron. Since the inner apron does not show it would probably not be noticeable, but would it be strong and work well enough.

What would you do?
