How you can make your own under the sea decoration

 
 First grab the thing you want to decorate,in my case i am going to decorate a wood letter A.
 Then paint it blue,any shade you want.
 While the paint is still wet put the silver glitter in lines across what you want to decorate,then some dark pink glitter and do lines like the silver glitter.
Then with a slightly darker blue than the one you used at the start,start  painting  lines with that darker blue,let that dry and you are done 

                                  🐠  YAY! 🐠

With this you can learn how to mix and make colors work and create something simple yet effective.
And remember don't go crazy with the glitter.What do you think you could do or add to make this decoration better?
