Look at
http://www.quilterscache.com/
There are many, many blocks of all styles here as well as a practice PP page.
Also, for PP, I've found Carol Doak's site to be very easy.

Cross my Heart and Crazy Heart Patch are fairly easy.
Don't forget to use the search function here on the board for PP tutorials!
