I wouldn't cut anything into 3 strips and then try to sew them altogether. I agree with the above comments and I'll combine them all. Start with 6 yards, and pleat it to your liking. Belt it on, wrap it up, and pin it up or tuck it back. There are many ways to wear a great kilt. There will be a lot of extra fabric but that's normal. Just try to decide how much is too much for you. If after trying out the 6 yards and it just seems like too much. I'd suggest make some more pleats first, but if that doesn't work, take off a half yard or yard. Just try to do as little "cutting" as possible. Good luck!
