I love PP! I tried lots of different websites and have a book by Carol Doak but found it difficult because I like to learn by watching. The best online tutorial I found to help me see and understand and watch while the lady did it was on Connecting Threads tutorials. I love PPing because all the points come together perfectly. It doesn't have to be done on just small blocks or items. I have made leaves, stars, etc. for large blocks. Try Connecting Threads and go to their tutorials and see if it helps you… imho
Happy PPing! Good luck and God bless.
