There are some tools in CorelDRAW that are very tough for me to master. The Mesh Fill is one of those. Luckily there is an amazing tutorial that shows you how to create a beer mug full of beer that is so realistic that you will try to grab it off your screen to take a drink. Unfortunately the original tutorial is in Russian and therefore hard for anglophiles to understand.
Thanks to automatic translation tools, we can read the tutorial in English. It may sound a little strange due to the computer translation, but you should be able to follow along and download the finished mug to explore.
