You're trying to make something that looks like this. First place the palms of your hands together. Now bring your elbows together and curl in your fingers to create two fists. Have a friend place a golf ball or table tennis ball in between your fists.

Now inch down the tips of your thumbs until they meet with the tips of your index fingers. Finally, have a friend place a pencil in between your closed forearms.
