Looking to get started with 2d patterns first then move into 3d- and Im a slower learner (not an excuse- but I know my limitations)... tried a search for stickies and getting started... no results

Anyone have a few "This is how a circle is expressed" or simple tutorial links? Thanks for the help and only hope I can contribute as much as I learn from you guys!

Thanks in advance
