Sean,
What I have not seen here is probably the best solution. go to Wal-Mart or Joann’s fabrics and buy some appropriate colored heavy duty thread and replace what you have. further color it with chalks and powders rubbed on. it is very difficult to take black thread and change its color.

Oh sure Al go and take all the fun out of it. I guess it you want easy and great results you could go this route. Its much more fun to try and figure out a harder way that yields lesser results.
