Amazon.com: Tree Storage Cover or Disposal Bag- For Christmas Trees up to 7.5 Ft Tall-Store Artificial Trees Upright & Decorated All Year Long by Elf Stor (Clear)

My husband put so many lights on the Christmas tree, that we decided to store it upright in hopes that it would make it easier for next year. We initially tried an expensive bag, but it wasn't wide enough and we eventually gave up in frustration. I came across this one, and the inexpensive price made me think that it was worth taking the risk. So that you can compare it to yours, our tree is 9 X 5.

It's basically one huge rectangle-shaped heavy-duty plastic bag. Looking at the sample picture, it looks like they put the bag on from the bottom - I don't know how they did that with the tree stand in the way. We ended up putting it over the tree and pulling the bag down from all sides until it was completely covered. It could also be that our tree is pretty wide and the branches hang pretty low; they kept flopping around as we tried to cover them. Because of that, this was definitely a two-man job; I can't imagine having done this on my own. Even then, compared to the expensive one we had tried, it slid down relatively easy.

Where we went wrong: Cover the tree wherever you're going to store it FIRST, because once it's covered, there's no real way to move it around comfortably; there are no handles, straps, etc. We stupidly did not think ahead, and it ended up coming apart inside the bag as we carried it around. We fixed it, but what a pain!
Pros: It does what it's supposed to - it covered our tree from top to bottom and met our expectations in both width and height. It will protect our tree from dust, etc., which is really all that we needed it to do. For the price, you can't beat it.
Cons: The branches caught on the plastic and made some tears here and there. So it's a cover, but do not expect any sort of major protection. You'll still have to find some way to close it up - we used a large tie-wrap. It looks pretty messy, but again, that's probably just us from having carried it up the stairs to our storage room and our ridiculously wide/low branches.
In summary: I would actually rate it somewhere between 3-3/12 stars and have no regrets in buying it. I can't rate it higher because I don't think that it's super sturdy, but for the money, it met our expectations and have no problem buying another one in the future.
