This is made of parts that I had around. All of it's reused!
Step 1: What you'll need
-12" x 15" piece of cardboard
-Glue (I used Gorilla glue)
-And magnets! (I used 3 magnets from some old speakers I disassembled)
Step 2: Start it
Step 3: Tape it up
Step 4: Glue it back together
It's best to do this all on a hard flat surface, unlike what I did. ;-)
Step 5: Trim and glue the magnets!
Trim the edges to your liking. If you need to you can trim off one of the rows of corks, I had to do this because the ends didn't glue as well.
now, just glue the magnets to the back of what you have so far and let it dry.
You're done! Now you have a magnetic bulletin board that you can stick to your fridge, garage door, or anything magnetic! I stuck it to the back of my front door, seeing as it's metal.
