  We attempt an extraction of the pretzelosity distribution ($h^{\perp}_{1T}$)
from preliminary COMPASS, HERMES, and JLAB experimental data on $\sin(3\phi_h -
\phi_S)$ asymmetry on proton, and effective deuteron and neutron targets. The
resulting distributions, albeit with big errors, for the first time show
tendency for up-quark pretzelosity to be positive and down-quark pretzelosity
to be negative. A model relation of pretzelosity distribution and orbital
angular momentum of quarks is used to estimate contributions of up and down
quarks.
