How many yards of tulle to make table skirt for round table?

To determine how many yards of tulle you'll need for a round table skirt, first measure the table's circumference by multiplying the diameter by π (approximately 3.14). For a standard table skirt, you typically want the tulle to drape down about 30-36 inches, so consider the height as well. For example, a table with a 60-inch diameter would have a circumference of about 188.5 inches; you'll need roughly 5.2 yards of tulle (since 1 yard equals 36 inches), plus extra for gathering if desired. Always round up and consider additional fabric for ties or securing the skirt.
