I bought remnants of the Atlanta Metropolitan Police pipe band tartan from Burnett's and Struth.

PS:
You'll want to adjust the fell line to 1/3 the length of the kilt. I believe we're all in consensus on that one. Correct me if I'm wrong, people.
- yeah, I sort of mismeasured my hem (well, actually, I plain did), so the fell is 3/4 of an inch too long. You can't notice so much when standing still, but when walking it is quite obvious. I may have enough internal pleat below the steeking to raise it a bit, but that project can wait...
