  One of the most powerful tools to probe the existence of cosmic defects in
the early universe is through the Cosmic Microwave Background (CMB) radiation.
It is well known that computations with causal sources are more involved than
the adiabatic counterparts based on inflation, and this fact has in part
hampered the development of fine detailed predictions. Analytical modeling,
while necessarily limited in power, may tell us the overall characteristics of
CMB from defects and hint at new features. We apply an analytical model for
textures to the study of non-Gaussian features of the CMB sky and compare our
predictions with the four-year COBE-DMR data.
