I made mine using a similar method.
I tacked on 1/2" fish netting on the back, over the shoulders and on the upper chest area of a WW2 bdu, I then cut, dyed and frayed hundreds of 4" - 12" pieces of burlap from burlap sacks different earthy tones and sewed and tied them on to where the netting was located.
I proceeded to sew 2 large patches of burlap on the lower chest/belly area of the suit, and spray painted them earthy tones.
I then made a hood by cutting off an old hood from a hoodie, tacking netting onto it, and sewing burlap strips onto it. I then made a face veil out of 1" netting and attached it to my hood.
After it was mostly together, I sewed on more burlap strips to places that needed a more natural shape, for example the sides of my hood and shoulders, to make the shape of my head blend in and look smoother compared to my shoulders.
As a finishing touch I took brown spraypaint and broke up the colour and outline of my arms.
I ended up ghillieing my left arm, and leaving my right arm clean, as I need to be able to move my right arm freely.
I made a ghillie rifle wrap too that isn't shown in the photo, using just netting, then sewing on burlap to it.
On a side note, I found that a good blend of artificial vs. natural foliage on a ghillie suit is about %40 artificial, %60 natural.
You can make ghillie pants using the same method, I would recommend without netting, as they will be too heavy and too hard to move around in.
And as a tip, try not to put foliage on your front right shoulder area, as that's where you rifle your gun, and if you do, you'll find your neck getting quite sore after a while, bending forward to look into your sights.
I would really encourage anyone who makes a ghillie suit to coat it in fire retardant afterwords, and store your ghillie suit indoors, unless you like bugs... lots of them.
On ANOTHER note... Here's a good camouflage theory lesson on silhouettes...
It's better to have a more rounded silhouette, so that the head and body sort of meld into a more natural blob-like... pile, instead of a head-like shape.
So smooth out the outline of the shoulders with more natural or artificial foliage.
