This is a really cool looking recycled plastic bottle fish lantern craft I found on a Japanese blog. They used a 2 liter plastic drink bottle. Unfortunately, there is no description of how the craft was made. It looks as if they glued green tissue paper strips all over the bottle. The fins and mouth appear to be other pieces of plastic likewise covered in tissue paper and glued on. The eyes might be painted bottle caps. It's a great idea. You could put a string of Christmas lights inside to make a lantern. It makes you think what other things you could make with the same idea. Follow the link below to see some other pictures including a blue fish. Have fun.
