I've ordered these 52" x 52" Square tablecloths for many events. They don't wrinkle, wash easily and add a spark of color as a "Table Topper" over a round table with a circular white tablecloth underneath. They are perfect for smaller tables just as a tablecloth also.
We have an event center with large round tables that have 80" white tablecloths on them. I use the table toppers to catch spills, and I can easily wash them and not the entire round tablecloth.
