  For conformal field theories in arbitrary dimensions, we introduce a method
to derive the conformal blocks corresponding to the exchange of a traceless
symmetric tensor appearing in four point functions of operators with spin.
Using the embedding space formalism, we show that one can express all such
conformal blocks in terms of simple differential operators acting on the basic
scalar conformal blocks. This method gives all conformal blocks for conformal
field theories in three dimensions. We demonstrate how this formalism can be
applied in a few simple examples.
