1. Go to this site and enter your text in the white box. 2. Choose ''spike left'' or ''spike right'' and choose the option ''transparent png''. Press the ''submit'' button and then click on ''save it''.

3. Open photoshop, go to file > new and create a 500x250 pixels file.

4. Add a background. I will use a gradient as background but you can use a solid color or a picture.

5. Go to file > open and search the speech bubble you made earlier on your files.

6. Drag the speech bubble to your header and position it somewhere.

You also can add more speech bubbles, or you can add a sharpen action or a psd or whatever you want to add on it. And That's all

This is my result:
