we have beer
Let's see a way to reuse beer caps and can rings to make some DIY pins....
a different way to make pins:
--edit: one more similar project
Step 1: Collect the (easy to Find) Materials
-1 bottle cap
-1 can ring
-1 safety pin
-1 tool to bend the ring
- anything to make the pin unique
- glue , marker, other common tools
Step 2: Bend the Ring
Try not to overbend it so you will need another one ring..
Step 3: Put the Ring in the Cap
Step 4: Bend the Cap Edges
if you want to keep the original color of the cap put some paper between cap's metal and the tool to avoid scratches.
