I typically do three- four wraps to bind in stuff and three wraps on the finish with a whip finishing tool.
However, on things like chernobyl ants, I will do up to 15 wraps on the areas where I am going to place the legs so that they are positioned correctly. I may do more wraps on EHC and the like...
On zebra midges, I use hundreds of wraps, hahahahaha.
