  We examine the role of spin twists in the formation of domain walls, often
called stripes, by focusing on the spin textures found in the cluster spin
glass phases of LaSrCuO and YCaBaCuO. To this end, we derive an analytic
expression for the spin distortions produced by a frustrating bond, both near
the core region of the bond and in the far field, and then derive an expression
for interaction energies between such bonds. We critique our analytical theory
by comparison to numerical solutions of this problem and find excellent
agreement. By looking at collections of small numbers of such bonds localized
in some region of a lattice, we demonstrate the stability of small ``clusters''
of spins, each cluster having its own orientation of its antiferromagnetic
order parameter. Then, we display a domain wall corresponding to spin twists
between clusters of locally ordered spins showing how spin twists can serve as
a mechanism for stripe formation. Since the charges are localized in this
model, we emphasize that these domain walls are produced in a situation for
which no kinetic energy is present in the problem.
