Is there a certain method to using an iron? What is the purpose of pressing and ironing? Pressing and ironing are two methods for using an iron that are often used interchangeably, but they have different definitions and purposes. The dictionary defines these two words as:

Ironing: The act or process of smoothing or pressing clothes, linens, etc., with a heated iron.

Pressing: To exert steady weight or force against; bear down on.

How does this apply to sewing and quilting? Ironing is moving the iron back and forth to smooth the fabric and take out wrinkles. The iron is not lifted from the fabric, rather it is rolling the iron over the top of the fabric. Ironing should be done cautiously; it can easily distort the fabric grain. Avoid ironing on lightweight fabrics where the fabric can easily be distorted.

If the fabric is wet or sprayed with starch, the dampness weakens the threads which will easily stretch out of shape if ironed. Always avoid ironing wet or damp fabric. For piecing quilt pieces and seams, ironing can stretch the fabric out of shape, which makes sewing the patchwork pieces together harder to do. Use ironing for large sections of fabric like quilt backings and garments.

Pressing is an up and down action with the iron. The iron is set down on the fabric for a few seconds, lifted and moved to another location, then set down again. This action is continued until the area desired has been pressed. Pressing is less likely to distort the fabric grain because the iron is not plowing over the fabric. When applying spray starch to fabric, always press the fabric instead of ironing it.

For piecing quilt pieces and seams, the point of the iron can be used to flip a seam to one side or flip the seam open. Then the iron is set down on the seam for a few seconds to press it into the desired place. Press fabrics so they do not become distorted or stretched out of shape.
