Step 5: Adding Hair
Ventilating is exactly like the latch kit rugs of ages ago. You feed a loop through one hole in the lace, and pull the loose ends through the loop and tighten the knot. This technique gave me lots of control about how the visible edges of the hair would look, and I'm really please with the final result.
Since facial hair is usually much coarser, I needed a completely different set of hair for the moustache. I scavenged a cheap, frizzy white wig, and sewed the hair directly through the latex.
