Draping a ceiling with fabric transforms an ordinary room into something extraordinary. Whether you're hosting a wedding, a shower or any other type of affair, fabric draping on a ceiling adds a touch of whimsy and romance to the venue. Choose a lightweight material such as tulle or organza in any one or combination of colors you'd like for this decoration. To successfully drape a ceiling with fabric, calculate the amount of material you will need prior to purchasing it.
Measure the length and the width of the ceiling and divide it by two. The fabric will hang from the edges to the center of the ceiling, so each panel will need to be half the total width and length of the area.
Add 15 to 20 percent to the calculation of the ceiling size. In order for the fabric to drape and create the desired whimsical effect, ensure you have more fabric than needed. These numbers will indicate the length of fabric that you need to purchase.
Measure the width of the fabric that you are using for the ceiling drapes. Determine how many widths of fabric you will require to cover the length and width of the ceiling. Multiply the numbers by two so that you purchase the proper number of panels for each side of the room.
