  • Put a bit of hot glue in the center of the flower, and sprinkle on some beads.

  • When making a ball at the end of the wire, be careful about the location of the flame.
  • Use a heat gun by 70 ℃ of setting. If you can't get that setting, use a hair dryer instead.
  • Ventilation is crucial when working with plastics and heat. Always be well prepared.
  • Be careful not to get burned by the hair dryer or lighter and heat gun.
  • Use hot glue and plastic glues safely.
  • When using plastics besides "PETE", the harmful smell sometimes goes out by heat. The physical properties are also different, so be careful.
