I am re-posting this awesome diy from the amazing, talented Wit & Whistle. It seems super easy to do and the results look great. Just think of all the other things you could apply this to!
To make clay garden markers you will need:
oven bake-able polymer clay rolled into 3cm balls (one ball for each marker)
appropriate baking dish (according to clay package instructions)
a rolling pin
a butter knife
rubber letter stamps
Roll each clay ball into a coil about 14cm long. Then flatten the coils to 0.5cm thick with your rolling pin.
Use the dull side of your knife to trim one end into a point (the dull side won’t leave behind serrated marks), and shape the edges of each marker with the flat side of your knife. Smooth out any imperfections with your finger, transfer the markers into your baking dish, and get your stamps out.
Stamp your garden markers, and bake them according to the clay package instructions. Polymer clay is plastic, so don’t worry about sealing it. Be gentle with your markers! Polymer clay isn’t the most sturdy material, but if you carefully plant them next to your herbs they should last.
