God I wish I'd had the opportunity to have it in bundles...my platoon told us what color rolls of burlap to get on a Friday and said "it better be right by Monday am" It was as much a rite of passage as anything else.
Some thoughts:
-Def leave room for, and use a lot of, natural veg as that is really what makes the whole concept work.
-That being said, use a lot of tan and brown vice green when you are putting on the threads. The natural temptation is to put on all kinds of green and stuff because it looks cool, the reality is that the tan/browns put you into the negative space which is where you want to be.
-Not sure what your application is for, but you may want to consider using something one piece vice BDU top/bottom. Either way you'll want to make a veil out of a boonie, but my point with the single piece is that for most uses this gives you enough coverage in all but the toughest stalks where people will get you b/c of your boots. I referenced it above, but the old Desert Storm era night desert parkas work well for a single piece ghillie-easy to get into, easy to get out of compared to top & bottoms.
Drop me a line if you need any help, pics, whatever. Ghillies are def a personal thing so enjoy making it your own.
