For city-dwellers who park in a different place each time they return home, a simple way to remember where the car is parked: a magnetic key-holding arrow for marking a street map on your fridge.
Step 1: Shape arrow from Sculpey, attach magnets
I used Sculpey polymer clay, pressing two magnets into it and then baking the clay and magnets together. When it cooled, I crazy-glued the magnets onto the arrow.
Step 2: Here's the front
Here's the front, with the key hook. I painted mine blue.
Step 3: On the map
Here it is holding a key on the map. That's where the car's parked.
