Then hold down the top right with shift, and tap the down arrow once. Then, click bottom left point, hold shift, join the objects by half. Go to brushes pallet and create a new brush. Click the spiral tool. Use the up and down with the mouse to select range you would like. Select the art brush, and click on it. Adjust to the settings you want, and you have a swirl on Adobe!
