For a professional look, our FHA chapter took chicken wire and draped it over the edge of the trailer to make a "skirt". We stapled the wire on the edge of the trailer, and cut it down( use gloves!!) to size, so that it made a nice "skirt" to hide the wheels. We then unfolded paper napkins and placed in their center a small wad of newspaper, and twisted them shut, leaving a good tail on each of them. Use just enough that you can twist shut the napkin and still fit/stuff the wad through the wire holes. You can do every other hole and the completed effect is beautiful! As for the sleigh, visit a furniture store for some really big cardboard! Use lots of tinsel, and dress the kids as elves or let them be the reigndeer!
