One advantage of square tablecloths is that homeowners can use the corners to secure the cloths to the tables. Round tablecloths are harder to secure, since they lack corners. Another advantage of square tablecloths is that they provide a more casual look on oval- and rectangular-shaped tables.
Homeowners still have the opportunity to show off portions of their oval- and rectangular-shaped tables when they place square tablecloths on top.
Homeowners can purchase square tablecloths in a wide range of fabrics, including cotton, linen and polyester. Polyester requires less maintenance than most other materials, since it doesn't stain and wrinkle as easily.
