We bought our tree a few years ago from TaiPan with the 25 percent off coupon they offer before Thanksgiving. We paid around $250 for a 12 foot pre-lit tree which is a pretty good deal!
To cover the wire in the middle, cut a small piece of ribbon, wrap around center area and hot glue to the back of the bow. From there it's ready to use as decoration!
So nice to have it decorated and ready for Santa's delivery!
