It was hard to get a good picture of this but it looks so BEAUTIFUL in person. You can really see the secondary colors shine through.
So all you have to do is cut about 3/4 inch strips of red, yellow and blue tissue paeper. Alternate colors vertically on a piece of Parchment Paper. Then alternate colors going horizontally on top.
Cut out and glue on the rainbow fish pattern and then cut it out when it's dry. Hang it in the window to see the beautiful colors shine through.
You can use any shape but I thought a fish would go well with
The Rainbow Fish book.
