Frequently asked questions
What interfacing weight should I use for different fabrics?
Use lightweight interfacing for delicate fabrics like silk or cotton voile, medium-weight for cotton shirts and blouses, and heavyweight for structured jackets and coats.
Should I buy extra interfacing beyond the calculated amount?
Yes, add 10-15% extra to account for cutting mistakes, pattern adjustments, and potential fabric shrinkage during pre-washing or construction.
Can I use fusible and sew-in interfacing interchangeably?
While both serve the same purpose, fusible interfacing bonds with heat while sew-in requires stitching. Choose based on fabric compatibility and desired construction method.
