  • Small Saucepan


  • 2 packets Knoxx powdered gelatin
  • 6 tablespoons water

2. Put the clear plastic on the surface

3. Make a barrier using non-toxic putty or clay or fondant.


4. Pour 6 tablespoons of water into the saucepan.

5. Sprinkle 2 packets of Knoxx into the saucepan.


7. Heat the mixture on low. Stir occasionally.

8. After gelatin has melted, tilt saucepan on one side. Skim foam off the surface.

9. Pour the gelatin onto the plastic sheet. Make sure it’s not too hot or it may melt the plastic.

12. Allow gelatin to dry overnight. Longer for a thicker sheet.

13. Once dried, gently remove the barrier and peel the edible gelatin plastic from the craft plastic.


14. Trim uneven edges with a pair of scissors.
