Ok, I did some re-figuring...
If I do a 3 inch pleat with a one inch reveal that will give me 7 inches of fabric times 21 pleats =147 inches. Add 8 inches for reverse pleat, 8 inches for under apron pleat=32 inches. 25 inches for under apron and 25 inches for over apron and that gives me a total of 229 inches or 6.36 yards not allowing for facings and such. Soooo... I don't have enough for that. I guess that's what I get for guessing at the yardage before I planned this and figured out how to calculate these things. My drop is 23 inches so I'm wondering if a standard piece of fabric is wide enough to make two lengths? It's not the double width stuff but it does look like it's pretty wide to me. It's material that's off the rack at the local fabric store.

Any advice given that 5 and 1/2 yards is it? Losing weight is not an option since my wife says that I have no butt as it is
Box pleats?
