The lip (side edge) of the table is thicker if the venues are using newer or plastic folding tables.
If you decide to rent a table skirt that uses clips make sure that you check the width of your table and let us or whoever you rent from know. Also, it would be helpful to tell us what your table is made of --wood or plastic.
I did find a site online that sold banquet tables that said in the description how thick the table skirt clips needed to be to accommodate their tables. It appears that most were 1 1/4", Which may not mean much to you, the bride, but it means something to us--the rental company. It means that all these little skirt clips that I paid $1.50 each for do not fit the newer banquet tables (mine are 1").
I was at a venue two weeks ago and ready to put on the table skirting on their (6) head tables and found that my clips didn't fit. Luckily I came prepared and had brought just large table cloths that went to the floor. They weren't as nice as the pleated ones but at least we were stuck with nothing considering I was almost two hours from Cedar Rapids. The other plus was the bride had Cinderella skirting that went over the plain white cloths so my fabric for that skirting covered up the plain white tablecloths anyway.
Here are a couple pics of some banquet tables and table skirt clips so you can see what I am talking about. I guess I will be on the search for different table skirting clips now.
You can see this plastic table has a thicker lip around the edge of the table
this one is more like what my clips will accommodate
