I have not made a suit. But I have made a poncho which provides easier movement. here is a pic where I used it as background when taking a picture of my RTAK. I looks kind of funky but works well in my AO when local foliage added using the para-cord ties I have attached.
I made an awesome one I use for paintball, I am 6 foot 1 inch tall 240 lbs and not only did I make an entire body raincoat style suit (no legs, more of a dress bottom) I had enough to make a head cover and a scarf for my gun as well. Here is the kit I bought:
it did take about 15-20 hours of tying and fabricating but the results look it. I used zip ties to make the pull over suit out of the 1 inch grid mesh that comes in the kit, its like 5 by 7 feet or so.
... which is what we did when making ours. Matter of fact, I'm glad you brought it up because it is an important safety concern on a lot of levels where a ghillie suit is concerned - for a lot of reasons.
Shannon's Bug Tamer Leafy Suit as the base. Add paracord ties, scraps from old cammys, tie in native vegetation. Yet to find another ghille that will keep the bugs off of you, limit human odor (charcoal models), as light and cool to wear in hot weather, offers as much freedom of movement, or conceals as well once modified. I've been close enough to a whitetail doe to smack her hindquarters, and I've caught squirrels with boonie hat in this get-up. In the deer stand in bow season you'll have squirrels trying to "climb" you and birds landing on you.
You'll need the parka at least. I use the parka and pants together with my own gloves. I replaced the mesh over the face part of the hood with a lighter color. The factory mesh is too dark and leaves a "black hole". I bought a 1/2 yard of coyote brown mesh at a fabric store for $2 and sewed it in on the wife's Singer.
