How do you apply skirting board to a curved bay??

[aspley]

Need to fix skirting into a curved bay (to give an idea of the curvature the bay is 10' wide by 2' deep). For the rest of the room will probably use tourus.
Question is, does anyone know of a product that can be worked to a curve of this nature or too what degree softwood skirtings be curved and how??

Any help will be gratefully received.

Our bay sounds similar in size to yours, the joiner made lots of saw cuts in the back of the skirting about 30-40 mm apart then eased the skirting into place using screws to fix it to the wall.
