well I have to say, from my experience, the store made plastic one's last the longest over burlap, and in the past 6-7 yrs my store made one's hav been out, no isue's with scareing deer at all
biggest issue with any stand IMO of getting ot causing deer to be wary of it, is if they bust you a few times in it, from then on, odds are most deer will start to look at it or be nervous about a stand they know people hide in, and that won't matter what material you wrap abot it

IF its flapping in the wind or making noise? that might cause them some worry's
but in time they adjust to that too, from my experence, heck for yrs I used to hang things to do just that in the off season to get der used to things moving up in the tree, worked great for me too!, even hung a dummy in a few for a while
and some of teh stands after that I could do jumping jacks in them and dder never paid no attention to me while hunting??

As for how do I add the PVC to tree stands, rather simple, I use bot stainless steel hose clamps and plastic zip ties

the best way to build one out of PVC is if you can build it while the stand is NOT up, and then mock it up to where you think you will want everything, and make it so you have a little to trim once the stand is up
but I have built them while a stand is up Too, just gets a little harder to hold things in place while mocking it up
on ladderstands its the easiest once up, over a loc on, as you have more levels to hold onto
normally when I do a loc on that is up, I take a ladder in with me, just to make life easier and safer
how I mount to the tree, all depens on shape of tree and such, but I have used branches to clamp/tie the PVC to or even used screw in steps to mount it to, as I like to have elbow room
things to think about when building a blind frame , is making sure you have enough clearance for your bow/X box, as when your at full draw, make sure there is room for the limb to extend after the shot, as if that limb isn't allowed enough room, bad things can happen
seen a guy shooting off his deck hit his bottom limb off teh rail and the string came off and all sorts of crazy happened and cost a bunch to correct, so I always used to take my bow with me, and get into any expected shooting positions, and make sure I had it out in front of me far enough to be out of the way
BUT!! doing this many times can mean giving up possibe CLOSE range shots due to it being in the way for sub 5 yrd shots due to angle and well the blind then in the way

you also have to think about ONCE you build the blind railing, HOW your getting into the tree stand
on ladder stands, I tend to have it so I climb up under it and thru it right in front
on loc on's
I used a bungee cord to allow it to have some flex so I could push down on railing and climb over
but it is something to think about


next, WHite PVC sticks out like crazy, even when covered with Camo Burlap(which fades due to the sun UV in about 2-3 yrs, so expect to replace about that often)
I used to build and then paint
but can tell you from experience its a ton better to paint the PVC off the stand first, than up a tree
I found Wally world flat black to be great and just .99 cents a can
has no shine to it at all, and blends in nice under the burlap
a few yrs back I did a tread here on a few of my stands I did, too, if you want to look for it??

I will be pulling all my stands soon , due to loosing the far I have them at
IF I remember when I am there , I will try and take a few pic's before I tear them down for you for some idea's if you want
ONLY have ladderstands up, as all my loc on's come down every yr and this yr didn't put any up, due to legal fight for the farm(which I sadly loss)
so no pic's of them?
feel free to ask me any ?'s you want, I did a bunch of stands like this!
