Oddly, my entire immediate family is allergic to evergreen trees. I knew I was - never made it to the Christmas Party in elementary school because of the lovely REAL trees they brought in. Back then, it was just a bad winter cold, so I stayed home with my families REAL tree. When my girls were little, we finally figured it out, and have been real tree free ever since. We had a fish net with large plastic pipe rings to hold it out like a tree for years. Then we bought a huge very real looking artificial tree. We gave that to our youngest daughter and now have a slightly smaller pre-lit tree. I do put some greens in wreaths outside - cedar branches and holly branches and berries and I make cone wreaths, which, oddly, don't seem to bother.
