I wish to differ slightly with Steve.
I agree with #s 1 through 4. My number five is readAlan H's X-Marks kilt manual.
6. read Alan H's manual again
7. read Barbara's book again
8. Get someone to measure you for the style of kilt you want to make
9. Get measured again - Have someone else do it, self measurement can lead to erors
10. Get measured again
11. reread the appropriate manual again and place bookmarks on the areas that you will be starting in.
12. Construct a kiltmakers thimble
13. layout and mark your material.
14. remeasure the layout and markings
15. Start sewing!
16. When completed, have someone take pictures of you in it. Front side with a step up, and of course a pleat shot.
17. Post pictures on XMTS.
Plan next kilt.
