Here's the tutorial I promised. I hope you enjoy it!!
First, I sketched my designs and taped them to the inside of the fishbowl.
Then, I painted on the designs, and painted the trim with yellow.
I mixed one part glue with one part water, and a lot of red food coloring. This mixture will create a sunglasses effect and allow the light to shine through the glass. I painted this on the rest of the bowl. Paint a lot of thin layers to ensure the mixture won't drip onto the edges.
After you are done painting you can bake the glass at 300掳 for 20 minutes to prevent paint from scratching off. I skipped this step, and taped the lights in. Use LED lights to prevent the glass from getting too hot.
This was the final product!!
