Please note that i am not a profecional! If i needed to i would make a fillit in the corner first. Wait till thats sticky and go from there if cosmetics aint importand. Just take a pointy bag fill it with thick paste and put a beat in the corners. Then make a nice concave curve in it with a spatula of some sort and wait. Then go oj with the cloth.
