making a pin badge from spare parts.
you'll need:
paper design
spare buttons
clear tape
scissors
craft knife
hot glue gun
safety pins

Step 1: Design

print or draw out your design.
I'm using a Photoshoped version of my works logo, printed on normal copy paper.
you'll need to cut it out very carefully with scissors

Step 2: Taping

once the design is cut out, stick clear tape over, make sure it's in the middle of the tape

Step 3: Sticking

add the taped design to the back side of the button as it's the smoother side.
I used a craft knife to trim around the edge of the button to remove the excess tape.

Step 4: Pins

finding small enough safety pins is tricky, but these ones are close to the same size as the buttons.
use sand paper to give the hot glue a better grip of the button.

Step 5: Hot Glue

putting a large amount of hot glue into the middle of the button allows you to sink the pin into it, so that it is covered all the way round.
make sure it's dry before moving.
