[HNW] Gold thread

[Carol Thomas]

I have a different gold thread question.  There is a piece of 16th c. 
petit point at the Met (not on display) that has a background which 
appears to be brown silk with a very, very thin gold wire.  It is 
runs on the opposite diagonal from the stitches in the needlepoint flowers.

I cannot tell how the gold stitches were done.  Tent stitch?  Woven in somehow?

Is anyone familiar with anything like this?
