A glance at the finished product.
Clear out some space for this project, it can get a little messy! Depending on the size of the display you want to make, gather a big chunk out of the air-dry clay.
Work it with your hands to make ANY shape you want with a base. Put it in the fridge for about 15 mins to firm up.
Using that old hotel key (any plastic card will do), make a slit into the clay.
Let harden for a complete 24 hours or more and it will also whiten up in color.
That's it! Add a photo as is or spray paint it a fun color to make it stand out.
