Fun challenge! I actually created my LO with a background paper and loved my creation. Then I deleted the background paper and loved it even more! Thanx for the fun inspiration!
At first glance, I thought this was a Christmas in July tree, but when I went back & looked again, I saw that it was more of a Fourth of July tree, with bows, ribbons & some mini-flags. The best part was that it was alongside a back road, not really close to any homes, making it a cool little surprise to run across.
This doesn't use a background paper, but it does use an overlay by Kate Hadfield over the white. Hope that's okay. If not, let me know and I will remove it.
