I made these heat sensitive wristbands with the idea of future use as a souvenir or promotion kit for various bands and shows.
Step 1: Find the Color-changing Materials
Thermochromic ink has various colors and easy to apply to different surfaces and materials.
Step 2: Paint and Design the Pattern
Choose the color and brushes that is good for the desired content. Mix and blend the color with thermochromic ink.
Step 3: Paint With Regular Color
Since the surface will be covered by the thermochromic ink, we can draw or print whatever images and information underneath.
Step 4: Finished Look
The last step is to use the mixture of the regular paint and the thermochromic ink to cover the whole wristband.
