What you will need:

Aluminum cans
Snips or metal shears
Hand files
Sandpaper
Found objects, paper, beads, etc.
Decoupage, two-part epoxy or other adhesives
Pin backs

Step 1.

Cut out the base of a soda can (just above the beveled edge). If you use snips, start from the top of the can. I used a piercing saw and cut straight across the bottom.

Step 2.

Use a hand file to even out the edges and sandpaper to smooth away any additional rough parts.

Step 3.

Decide which found objects you would like to adhere inside the base, and which adhesive is most appropriate. For example, if you use fabric or felted beads like I did, a glue gun will work. You can use decoupage for paper, or clear polyester casting resin for embedding objects like small flowers or glitter. Be sure to follow the instructions, as some adhesives are more toxic than others. After affixing your object collage, allow it to dry.

Step 4.

Attach the pin back with a two-part epoxy. You may have to bend it a bit with pliers to be sure it fits the base.

Step 5.

Put on your brooch and show it off!
