R/W/G Rayon thread

Hi Guys,
   Does anyone know of a source for cones of red/white/green variegated rayon
machine embroidery thread?  I want to embroidery the SMDGDs name on some
holiday tops I bought her and thought doing it in variegated r/w/g  thread
would be neat.  I have some r/w/g variegated cotton quilting thread but would
really like rayon.  I have posted over at RCTN and at the machine embroidery
site asking.  I should probably post over at RCTS too!  Getting to be too many
places to ask these questions -- LOL!
   I have googled but get a bazillion links.  I have already spent close to an
hour and am not having much luck.  Thought one of you might have some ideas. 
Thanks & CiaoMeow >^;;^<
