Here's where I started to learn how to PP.
Start Quilting 3 - Practice Paper Piecing (quilterscache.com)
I watched various basic videos online, and paid attention to tips and hints here on the QB. That first basic block is a good one to get you started. Lots of other PP patterns on that site. Some are more basic for beginners. Some more difficult. But don't let your newbie-ness discourage you, if you want to do something!!!!
As a word of warning .... you will find/hear/see many different ways of how to PP. Take a bit from each and don't feel bound to only one way. As time went along, I developed my own rhythm and style. You will too.
It's a wonderful quilting technique ..... for me it's an easy, lazy way to quilt, when I am tired and don't really feel like paying attention to detail. Sometimes I feel it has made me a lazy quilter, as I will opt for PPing at times, just so I have all those perfect points, and straight lines. (yes, I still do my fair share of non-PPing!)
Good Luck ... and most importantly, have FUN!
