This a shipping option to ship your felt not folded. 

This a flat box, works best for 18x22 (1/2 yard) cut. 

The charge is for the box ,and the extra shipping charge that is charged due to the size.

The full charge will come up at the check out, when your full order is finished.

If you get this option, while buying 1 yard felt, it will be automatically assumed that you would like it folded in half to fit the parameters of the box.
