One thing I keep seeing everywhere is cornstarch clay plant markers. They’re easy, cheap, and honestly fun to make.

These little plant tags help you remember what you planted, especially when seedlings all look the same.

Ever planted basil and cilantro and then forgot which is which? Yeah… same here.

In this guide I’m sharing 12 beginner-friendly ideas for cornstarch clay plant markers that you can make at home using simple tools.

Some ideas use stamping tools, others rely on hand carving. None of them require fancy skills.

Let’s get our hands messy.

1. Classic Stamped Cornstarch Clay Plant Markers

What you need

Step-by-step process:

1. Add baking soda, cornstarch, and water into a saucepan.
   
2. Heat on medium and stir constantly.
   
3. The mixture thickens quickly and starts looking like mashed potatoes.
