The 'pyjama stripe' is the subset of the plane consisting of a vertical

strip of width epsilon about every integer x-coordinate. The 'pyjama

problem' asks whether finitely many rotations of the pyjama stripe about

the origin can cover the plane.

I'll attempt to outline a solution to this problem. Although not a lot

of this is particularly representative of techniques frequently used in

additive combinatorics, I'll try to flag up whenever this happens -- in

particular ideas about 'limit objects'.
