Here's a link to pictures of my latest bug bivvy.
As I posted somewhere before:
I just finished making my second bug bivvy, a noseeum tube, (2 pieces of 125" x approx. 59" hemmed black noseeum sewn together, 96" #5 zipper with 2 reversable pulls on one seam, drawstrings on the ends). It was pretty easy to make and looks good, imo.
BTW, this was for my speer-type hammock, top loader.
I'll post some pictures in the gallery.
