Hi,

I am trying to find a place that can put my corporate logo on a
"standard size" white window curtain.  The idea is that the curtains
would always be closed, letting some light through (as they are white)
and showcasing the large logo in the middle.

A quick search didnt reveal any place I could get this done. I am
looking for places that will do this specifically -- not just a list
of curtain shops.  Pls screen them as appropriate and respond with at
least 2-3 options.  I would simply provide camera ready art.  Would
prefer that it is embroidered or sewn on, as opposed to some other
process.

Los Angeles area preferred, but anywhere in the US is fine (as long as
they will do mail order).  Thanks!

try a local embroidery shop - or sports awards - 

They would need to make a computer file from your logo, then could
apply it to as many as you need.
