In the following tutorial you will learn how to create a liquid soap bottle illustration. We’ll start with a 3D base and add details and Blending Modes to create a refined stylized vector illustration.
Step 1
Create a New document by pressing Command + N. Enter 600px in the width box and height boxes then click on the Advanced button. Select RGB, Screen (72ppi) and make sure that the "Align New Objects to Pixel Grid" box is unchecked before your click OK.
Enable the Grid (View > Show Grid) and the Snap to Grid (View > Snap to Grid). Next, you’ll need a grid every 5px. Go to Edit > Preferences > Guides > Grid, enter 5 in the Gridline every box and 1 in the Subdivisions box. You can also open the Info panel (Window > Info) for a live preview with the size and position of your shapes.
Do not forget to replace the unit of measurement to pixels from Edit > Preferences > Unit > General. All these options will significantly increase your work speed.

Step 2
Using the Rectangle Tool (M), create an 80 by 170px shape, fill it with a random grey and go to Effect > Stylize > Rounded Corners. Enter a 5px radius, click OK and go to Object > Expand Appearance.

Step 3
Focus on the top side of the shape made in the previous step. With the Rectangle Tool (M), create a 40 by 20px shape, fill it with a random grey, place it as shown in the following image and go to Effect > Stylize > Rounded Corners. Enter a 5px radius, click OK and go to Object > Expand Appearance.

Step 4
Using the Rectangle Tool (M), create a 30 by 15px shape, fill it with a random grey, place it as shown in the following image and go to Effect > Stylize > Rounded Corners. Enter a 5px radius, click OK and go to Object > Expand Appearance.

Step 5
With the Rectangle Tool (M), create a 10 by 25px shape, fill it with a random grey and place it as shown in the following image.

Step 6
With the Rectangle Tool (M), create a 40 by 5px shape, fill it with a random grey and place it as shown in the following image.
Switch to the Ellipse Tool (L), create a 40 by 10px shape, and place it as shown in the second image. Select it along with the rectangle made in the beginning of the step and click on the Unite button from the Pathfinder panel.
Next, you need the Round Any Corner script. You can find it in the Vectortuts+ article 20 Free and Useful Adobe Illustrator Scripts. Save it to your hard drive, return to Illustrator and grab the Direct Selection Tool (A). Select the two anchor points highlighted in the third image and simply go to File > Scripts > Other Script. Open the Round Any Corner Script, enter a 3px Radius and click OK. In the end your shapes should look like in the fourth image.

Step 7
Reselect all the shapes created so far and click on the Unite button from the Pathfinder panel. Fill the resulting shape with R=235 G=235 B=235.
