  Fusible and non-fusible interfacing
• How is fusible interfacing applied?

  Using heat and pressure with a hot iron
• What happens if the wrong weight of interfacing is used?

  It can result in puckering of the fabric
• Why is it important to test the fusing method before applying interfacing?

  To check temperature and fabric reaction
• What is the purpose of bias binding?

  To finish raw edges of a garment
• How can fringing be described?

  Decorative strips that add movement
• What materials can fringing be made from?

  Cotton, silk, leather, and beads
• What is lace used for in garment construction?

  As a delicate trim with open designs
• What is the purpose of beaded trims?

  To add lustre and emphasize style lines

  To define shapes or add strength
• What is the function of Velcro® in garments?

  To provide a quick and easy fastening
• How should D-rings be used in fastening?

• What are hooks and eyes used for?

  As a discrete two-part fastening

  • Requires wider edges for alignment
• What are the characteristics of D-rings and their use in fastening?

  • D-shaped loops for adjustable fastening
  • Made from metal or plastic
  • Secure fastening relying on friction pressure
• What are the characteristics of hooks and eyes as fastenings?

  • Two-part metal fastening
  • Discrete and often used in waistbands
  • Sewn on by hand using buttonhole stitch
• What are the characteristics of fabric and ribbon ties?

  • Decorative two-part fastenings
  • Used to finish necklines
  • Edges may need to be finished to prevent fraying
• What is the purpose of a hook and eye fastening?

  To fasten edges of fabric together
• How does a curved loop eye differ from a straight bar eye?

  A curved loop is for overlapping edges
• Where are hook and eye fastenings typically used?

  At the top of zipped openings
• Why should stitching not go through to the right side of the product?

  To ensure the fastening remains secure
• What materials can be used for two-part decorative fastenings?

  Ribbon, fabric, or braid

  To prevent fraying
• What are frog fastenings made from?
