  In the analysis of \epsilon^\prime/\epsilon it has been traditional to
consider the isospin-breaking effects arising from electroweak-penguin
contributions and from \pi^0-\eta and \pi^0-\eta^\prime mixing, yet additional
isospin-violating effects exist. In particular, we study the isospin violation
which arises from the u-d quark mass difference in the hadronization of the
gluonic penguin operator, engendering contributions of an effective \Delta
I=3/2 character. Using chiral perturbation theory and the factorization
approximation for the hadronic matrix elements, we find within a specific model
for the low-energy constants that we can readily accommodate an increase in
\epsilon^\prime/\epsilon by a factor of two.
