I make my camo kilts with the DPM strips torn across the material, rather than with strips cut parallel to the selvage - as it is directional. With a wide fabric it is also less wasteful to cut it across

Joining 4 strips gives you about 7 yards of kilt, and if you need a drop of about 24inches, you would only need - at the most 3 yards of the material.

The 25 yard bolts on offer would probably make 8 kilts - though if it is light stuff you could double it - then you'd not need to hem it, and it would make just 4 - 2 to keep and 2 to sell perhaps?
