Kind size duvet material (crouch end, N8)

Hello! Can anyone use this material? It's a king sized duvet cover that is wearing out and can't be repaired any more at the top end. The rest of the fabric is in pretty good nick. 100% cotton. It has a pale green tint to it. One side is plain and the other has a weave to make a pattern. Hopefully you can see it in the picture. I'm including the 2 pillow cases too, as extral material.
