Lightly sand the Shrink Plastic on both sides then using the
pattern piece trace the heart shape onto your Shrink Plastic and
cut it out. Punch a hole a fourth of an inch inside the dip of the
heart. Color your heart with either colored pencils or acrylic paint.
Remember as the plastic shrinks the color will become darker and
more intense.
On the front side of the heart write with a permanent fine point
marker "I" place a heart shape and the letter "U". Use the picture
as your guide.
Following manufacturers instructions for your Shrink Plastic
place it in the preheated oven for the specified length of time.
Your heart is finished when it has become completely flat. Be sure
to get adult help for the shrinking process.
Place the metal key chain through the punched hole after your
shrink heart has completely cooled. This makes a nice Valentine
gift for family and friends.
