Novice CS Adobe Illustrator designr

I have been using CS4 Adobe Illustrator for about a year now to design Tshirts, logos for duffle bags, mugs, water bottles, etc. Before CS products, i was a Corel user. Been very successful learning on my own and using uTube tutorials to figure out what I need to do or accomplish and putting together designs that are basic concepts. Having lots of fun and enjoy learning everyday with each and every project.
