what supplies you need for this are really simple.
You need five or six 3/8"x20"x30" foam boards, there less than a buck fifty each. Kinda like what you use to use for science projects. You need a Mylar emergency blanket, they cost less than 2 bucks. You need a roll of duct tape. You need scissors.
Now what I do is take the emergency blanket stretch it out on a hard floor type it so its wrinkle free and tight. Then I'll lay the foam boards down where they will go once they're glued. Once I know the position they're going to be in I'll take them up one at a time and spray it with the adhesive and then stick it to where it's going to go. Once all of them are down I just start cutting them apart either with scissors or a razor knife if you prefer.
I'll post later some of the things I've used this stuff for but it turns out really well and cheap. To do the whole thing the first time it may be about 20 bucks but then its more like 10 on the next go around since you already have the adhesive and duct tape, and you cover a lot of space.
Let me know what you guys think.
