Here's a project that the kids will love.
What you need:
RAINBOW FISH blackline (click for bigger image). I like to print it out on cardstock or heavy construction paper.
Tissue paper (you will need red, orange, yellow, green, blue and purple) cut into small squares
First, cut out the fish. You could actually save this until the last step. I tell you how at the end.
Second, get your glue ready. Just dilute it with water. My kids call it glue paint.
Third, take the tissue paper and glue it down with the "glue paint". Don't worry about going over the edges, you can just trim those later. That is why you can save cutting out the fish until the end. You can save yourself one cut.
Lastly, lay your fish out until it has dried and then find a place to hang your RAINBOW FISH where everyone can enjoy it!
