[Strawbale] Welded wire mesh in Lime plaster

[Mark Frazier]

Let me get some clarification on this. Are you saying that you will  
NOT be "wrapping" the entire exterior of the bales in WWM,
corner to corner, top to bottom, as suggested in the video from  
strawbale.com?

for example, if there is a 4x post running vertically, then you will  
be stapling a 20" wide piece of WWM to it (with 8" on either side of  
the post), and that's
all for the WWM?
