Ok, I am not great at math and do not have easy access to various table cloth sizes and the tables at my reception, so I'm hoping you crafty brides will have a sense of this.
My venue has 70" round tables. Smartyhadaparty has table clothes for the less than what I would pay to rent, so I am leaning towards buying table clothes (if I can sell them even at half of what they cost me, great, if not, I'll donate them to my local thrift store). The tables are basic plastic with metal legs so I want my table clothes to go down to almost the floor if possible (without a big mass of fabric on the floor). What size do I need? 120"? 132"? Is there some standard rule of thumb for figuring that out? I am also going to need some rectangular table clothes for cake table and whatnot and haven't found out what size their rectangular tables are yet.
