I would use the point to point lassoo tool in Paint Shop Pro, then if its version 9, click the selections tab, and find the smooth function, and apply a 15-20% smooth to your point to point selection. Then fill in with white, then do a compress, by however thick you want the white lines to be, then make it red.
And as Gordan Ramsey would say!
Click, point, smooth, fill, contract, fill, DONE!! :0D
