  The tetragonal YbNi$_4$P$_2$ is one of the rare examples of compounds that
allow the investigation of a ferromagnetic quantum critical point. We report in
detail on two different methods which have been used to grow YbNi$_4$P$_2$
single crystals from a self-flux. The first, a modified Bridgman method, using
a closed crucible system yields needle-shaped single crystals oriented along
the $[001]$-direction. The second method, the Czochralski growth from a
levitating melt, yields large single crystals which can be cut in any desired
orientation. With this crucible-free method, samples without flux inclusions
and a resistivity ratio at 1.8 K of RR$_{1.8\rm K}= 17$ have been grown.
