Cornstarch Glass Floral Hearts & Flowers: A Stunning DIY Craft That Looks Like Stained Glass
This “cornstarch glass” craft is a popular DIY decoration project that creates delicate-looking hearts and flowers with a stained-glass effect—without actual glass. It’s safe, inexpensive, and perfect for home décor, gifts, or seasonal decorations.
The secret material is simple kitchen cornstarch, which helps form a translucent, clay-like medium that can be shaped and colored.
What Is “Cornstarch Glass”?
It’s not real glass. It’s a homemade modeling mixture (often called cornstarch clay or faux porcelain) that dries into a firm, slightly translucent finish.
When colored and cut into shapes like hearts and flowers, it can mimic the look of stained glass when light passes through it.

- Cornstarch
- White glue (PVA glue)
- Water
- Food coloring or acrylic paint

- Wax paper or parchment paper
- Straw or skewer (for holes if hanging ornaments)
Basic Recipe for Cornstarch Clay
- Mix:
- 1 cup cornstarch
- 1 cup white glue
