Make a sphere of external diameter, then difference the sphere of internal diameter, and then the differences of the extruded spaces around your flat pattern, rotating as required. You will most likely have to manually adjust the edges, scale, etc. to avoid hard steps when trying to align the individual shapes, but it depend on the patter you are trying to wrap. For centuries, cartographers have struggled with representing a pattern on a sphere onto a flat plain, so you'll have to compromise. You may be able to use some more automatic positioning/scaling whatever, but probably not. I've attached the start of a sort of example.
