Fill a 10 gallon bucket with spackle mud, then coat a long-handled paint roller with the spackle mud.
Roll spackle mud over an 18-inch wide section along the length of the ceiling.
Wipe an 18-inch wide spackle brush in a half-circle swirl, then move the brush to the edge of the swirl and repeat the process to create a row of half-circle swirls along the spackled area. Position the swirls so that the rounded sides face the wall.
Roll a second 18-inch section along the length of the ceiling directly next to the finished half circle swirls.
Wipe the brush over the second spackled section, positioning the half-circle swirls so that the rounded edge overlaps the first row of swirls by 3 inches.
Repeat this process until the entire ceiling is covered with old-fashioned swirls. Drag a scraper along the edges of the ceiling to remove any excess spackle. Allow the ceiling to dry for 18 to 24 hours before painting the ceiling, if desired.
