  • Large piece of fabric
  • Scissors
  • Many bamboo skewers
  • A patch of grass that will NOT be walked upon (This is important as stepping on the bamboo skewers could cause injury.)


  1. Cut the letters of a name or word (or another image, e.g. a heart, a star) out of the fabric.
  2. Lay the fabric letters flat on the grass spelling out the word.
  3. Use the bamboo skewers to pin the fabric in place.
  4. Wait several days.
