1) Clothes pins (can be found in a local store. I've seen these in Maxima/ IKI)
2) Washi tape
3) Magnets (available at Tiimari)
5) Stationary knife
This is super easy to make. First, stick the washi tape on to the pin.
Use the stationary knife to trim the excessive washi tape.
Glue a magnet to the other side of the pin and you're done!
You can use it to hold any important notes, nice cards or some pictures!
