In this talk, I'll present how form factors with Wilson lines can be bootstrapped out of free-field wavefunctions. A single-line shift allows to recursively construct the form factors in a conceptually clean and computationally efficient way. This leads to an MHV expansion for the form factors that resembles a soft expansion. As an example, I'll recover the 1->3 splitting function for gluons.
