Ironing requires careful preparation and execution to protect both the textile material and the user. Kenyan fashion designers working in workshops or boutiques should follow systematic procedures for best results.

  1. Read and Understand Fabric Care Labels: Check garment tags for recommended ironing temperatures and special instructions to avoid damage.
  2. Set the Iron Temperature Appropriately: Adjust the iron to the fabric-specific heat setting; allow the iron to fully heat before use.
  3. Prepare the Garment: Lay the garment flat on a clean ironing board; smooth out major wrinkles by hand.
  4. Use a Pressing Cloth When Needed: Place a cotton cloth between the iron and delicate or dark fabrics to prevent shine and scorching.
  5. Iron in Sections: Begin with less visible areas such as inside seams, then move to larger exposed surfaces like collars and sleeves.
  6. Use Steam or Spray Water as Appropriate: For tough wrinkles, apply steam or lightly mist the fabric to relax fibers before pressing.
  7. Avoid Over-Ironing: Do not hold the iron in one spot for too long; move steadily to prevent burns or fabric weakening.
  8. Hang or Fold Immediately After Ironing: To maintain smoothness, place the garment on a hanger or fold neatly after cooling.
  9. Turn Off and Store the Iron Safely: After use, unplug the iron, allow it to cool completely, and store it in a dry, safe place.
