Before cutting your sewing patterns, it is important to take a few preliminary fabric preparation steps. One of these simple but very important steps has to do with ironing the fabric prior to aligning and cutting your sewing patterns. Ironing will not only facilitate an accurate pattern cut and placement, it will also provide a more enjoyable working process.
As a rule of thumb, always iron any fabric creases prior to aligning, pinning and cutting your sewing patterns. Most fabrics that come off a bold or roll are fairly wrinkle-free, it is usually the folding creases that will require some ironing out. When a fabric has been stored in folded position for an extended period of time (on a bolt, for example), you may find that the fold crease does not come out even with high heat and extensive steaming. In this case, it is important to avoid this crease when aligning and cutting your patterns.
To avoid stubborn folding creases while preserving as much of the fabric as possible, use a double lengthwise fold to align and cut your full and cut on fold patterns. The simple folding technique brings both fabric selvage edges together at the center crease location which naturally helps you avoid it in the pattern-alignment process.
