You've got a perfect start there, nice work! At a click this would be good. You'll want much softer edges if you want to trick deer at close range.
I'd suggest NOT washing/drying, but if you insist just do a good soak with a garden hose, then put it in a laundry bag before you put it in the dryer (or even better, hang dry it.) Check it every ten minutes or so. If you just toss all that burlap in a dryer it will either clog vent or do that and catch fire.
Personally I'd strip out all the horizontal burlap so the vertical strands hang nicely and fuzz out good for you. Of course that will triple your build time, but it looks really good.
You could mix in some untwisted hemp twine, it's a nice light absorbing texture to augment a jewt suit. Just don't over do it.
Finally, if you don't use any of the methods above to wear it in, just soak it with a hose and tie a 10' rope to your trailer ball and to the different parts of your suit and do some donuts in the gravel with it whipping around behind you. You really gotta do something to wear it in. Check it frequently if you do this, "wearing in" and "wearing out" is a fine line.
Oh, and x3 on clearing a nice spot for your string to clear.
Once your suit is all fuzzy, don't be afraid to mix in leaves, weeds, etc, each time you head into the field.
