Lew, thanks for the positive feedback....
To anyone interested here's the one you tube video I found the most helpful. (BELOW THIS PARAGRAPH)..... I didn't follow it word for word, but it's not that challenging, and the materials are inexpensive so you can't get in that much trouble, or lose a huge investment. I found it worked better to open the filter material up... it starts around a 1/2 inch thick, it was over an and a half thick when I was done pulling it apart. I just don't choose to spend $15, or more per tree. There's some really nice trees on the market but they're expensive.

Dave, I found it worked just as well to glue the branch structure to the trunk then paint the whole tree.... after the paint dried, I used a cardboard straight edge like 6 " x 18 " and held the tree behind it so I'd only spray the outer branches and not bury the trunk with the glue. That way the static grass only sticks to the branches and doesn't adhere to the main trunk. We added the dead branches at the bottom after the static grass was applied. Just scrap branches from a wild cedar tree in the woods in the back yard.
Mark, thanks for your thoughts. The shoulder is really weak when my arm is away from my body and especially raising it, but it is what it is... Fortunately it doesn't ache all the time, but at 13 months since surgery it's probably about as good as it's going to get.
The product from Walmart that I used is called Natural Aire, it's 20" x 30" dark green in color, I think it cost around $6.00 +/-.... I have made 5 trees to date and have used about 1/3 of a single filter.
