LED’s  !   Light  Emitting  Diodes  

!   Emit  light  when  electricity  runs  through  them  

!   Only  work  if  the  electricity  is  going  in  the  right  direction  

!   If  you  connect  the  long  wire  to  the  positive  side  of  the  battery  and  the  short  wire  to  the  negative  side,  it  works  

!   Connect  it  the  wrong  way,  though,  and  nothing  happens

Step  1:  trim  the  felt  to  fit  your  wrist

Step  2  –  add  snaps  !   Using  conductive  thread,  

sew  one  half  of  the  snap  near  the  end  of  the  strip  (sew  lots  of  conductive  thread  through  the  loops  of  the  snap  to  make  a  good  connection  when  the  snap  closes)  

!   On  the  back  side  of  the  strip  sew  the  other  half  of  the  snap  so  that  when  the  strip  is  closed  in  a  circle,  the  two  halves  snap  together

Step  3  –  add  light  !   Cut  a  slit  in  the  strip  for  the  

LED  lighs  

!   Poke  the  LED  light  bulb  through  the  hole  so  the  metal  is  on  the  back  and  the  bulb  is  on  the  front  of  the  bracelet

Sew  lights  &  battery  holder  

!   On  the  back  of  the  bracelet,  sew  the  positive  (square)  side  of  the  LED  to  one  of  the  snaps  

!   Sew  the  positive  side  of  the  battery  holder  (the  one  with  the  three  plastic  prongs)  to  the  other  snap  

!   Sew  the  negative  (round)  side  of  the  LED  to  the  negative  side  of  the  battery  holder  

!   Slip  the  battery  into  the  battery  holder  negative  (rough)  side  down

Decorate  !   Add  decorations  to  the  

front  of  the  bracelet  –  fabric  glue  or  felt  glue  is  great  for  this  

!   Snap  the  bracelet  on  your  wrist  and  watch  it  light  up
