Call for Artists, Making Money at Juried Art Fairs, Craft Shows and Festivals
There've been a couple threads about making cement weights out of PVC pipe. I'm actually making some this weekend with a friend. There was another thread about some manufactured weights, but I can't remember the names of the companies. One other resource is the sand bags at Flourish.Com. If you get them, use pea gravel, not sand, to fill them up. Sand leaks!
Yes, you will need weights. How much depends on what kind of displays you have inside. I use steel gridwall and it adds about 150 pounds to my tent, so my weights are just extra protection. Another suggestion would be to get the Sta-Bars from Flourish. They are great at stiffening the EZ-Up or Caravan tents. I looked down at a long row of tents at a show in 2008, and mine was the only one not swaying. The next year 5 or 6 of the other participants had bought the Sta-Bars! Best $150 investment I've made in the show area!
I'm sure there's a discussion here about tent weights, not sure where to tell you to look- try the search box in the upper right hand corner
