Here are two words to help you create perfect pleats: freezer paper. Follow these five easy steps to use regular freezer paper from the grocery store to create beautiful little pleats.
Cut a length of fabric the width of your freezer paper.
Cut a length of freezer paper the width of your fabric and mark your pleats on the back (non-shiny side) of your freezer paper (example shows 2” pleat with 1” spacing).
Pin and press the freezer paper to the back of your fabric. The waxy coating on the back of the freezer paper will create a temporary bond between the paper and the fabric.
Press pleats one by one. In our example, we close the 2” gap (i.e. we bring one of the lines to match up with the other line) and then press it in place until all of your fabric is pleated.
