I have made most of the things we take out to put on the grave of our son... wreath's (not just Christmas ones), other holiday decorations (Valentine's, Easter, 4th of July, Halloween, birthday) and I hang them from a wire 3 leg stand.
Many years ago we had his birthday piece stolen, so since then I don't leave much out there, I put somethng out and then take it when we leave. In December every year we take out a Christmas wreath and leave it for the month, so far that has not been taken, but so many people have them there that hopefully the chances of ours being stolen is slim.
