This is a simple craft work which includes the work of glace papers and colors.
Step 1: Color the Background
Firstly, take a white drawing paper and color it with blue or light green or whatever you wish your water to be .(Try coloring apart blue which is shown here and get creative!). I have used crayons. You can use water colors to make background look more prominent.
Step 2: Take Three Glace Papers of Different Colors
Next in step includes the glace papers. Take three different colored glace papers and stick it with a glue in a vertical direction. Look out for next step to learn how to rock and roll the fishes.
Step 3: Roll Your Fishes
This is the main part of all the parts. Start folding a single glace paper upside down and keep doing it until your paper is folded it the end. After that bend your paper from the middle so as to give it a shape like that of a Chinese fan.
This is how you have to roll those three glace papers which is now a single unit and paste it from the center.
Step 4: Make Your Fishes Swim.
Now to give it a final go, put eyes on those fishes with a help of small paper and marker and paste it. To give it a more realistic effect place different sizes of fishes and don't forget to give them their tails also.
