Open Houses are tough enough to set up. On a windy day, it can be very frustrating to set up all your signs just to find them blown over when you go back to pick them up. You might be wondering why you had little or no traffic in the open house for a few hours. Well, if people don't see your signs, they won't come.
I had a friend make some very cool weight bags for my open house signs so they won't blow over. She made canvas bags which I then filled with rocks and sand.
Now if I don't have people coming through my open houses, I know it's not because the signs blew over.
