Joe,
The general way to accomplish this is pick a color and make that the permanent construction. The fabric holds the noodles in place, so make it tight when assembling. A staple gun works great to hold the fabric in place, add aluminum angle if you feel a need for extra hold. Then make the skirt out of the other color. Don't use foam to hold everything in place it is not an allowed bumper part and it will permanently crush when hit.
