I decided to make a completely solid color for the thermochromic ink. I thought black was pretty nice when I did the swatch tests during class. I embroidered a pair of eyes that would appear when the circuit was turned on. Unfortunately I think my circuit is broken because nothing appeared. So I put the 9V battery directly to the embroidered pattern and I noticed that the thread quickly heated which caused to make just blotches on the paper. Perhaps I need to make the eyes bigger or maybe it would have worked better with the circuit.
