[HNW] learning blackwork

[Lisa Tyson]

I would recommend the British publication, 
New Stitches, sold at many bookstores like
Barnes & Nobles or Borders.

http://www.newstitches.com/

Just about every issue (or at least every other
issue) has a small blackwork project and 
instructions on how to do blackwork. 

Blackwork archives has a nice set of
instructions on how to do the double running stitch

Good Luck.
