Common Mistakes to Avoid

1. Inaccurate Measurements

Reason: Incorrectly measuring your body can lead to a dress that's too tight, too loose, or has ill-fitting proportions.
Solution: Double-check your measurements and use a flexible measuring tape to ensure accuracy before cutting the fabric.

2. Ignoring Fabric Grain

Reason: Cutting fabric pieces off-grain can result in a garment that hangs unevenly and looks distorted.
Solution: Always align the fabric selvedge edges and ensure the lengthwise grain runs parallel to the long edges of your pattern pieces before cutting.
