A crinoline is a type of petticoat made out of stiff fabric used to make dresses and skirts fuller. Sewers can create their own crinolines using the following steps.
Measure the desired length of the crinoline. Divide the length into three different layers. Add a few extra inches to accommodate seam allowances for each layer.
Measure the waist to determine the width of the crinoline. For the first layer, add some extra inches to the waist measurement. Each subsequent layer should be wider than the previous one to create a tiered effect.
Cut the fabric according to the length and width measurements from the previous steps to create long strips. Cut the shortest strip out of jersey and the remaining strips from the tulle.
Sew the short ends of each strips together to create the tiers.
Gather the top edges of each tier. Sew the second tier to the top, narrowest tier. Add each tier, working towards the bottom of the crinoline.
Turn over the top edge of the crinoline and hem it in place, leaving enough space for the elastic. Leave part of the seam open so that the elastic has space to enter the casing. Cut a length of elastic to fit the waist measurement and feed it through the casing. Close the rest of the seam.
Add a hem to the crinoline to keep the tulle from snagging on tights.
