I started with the QuiltersCache PP instructions.
And discovered, it wasn't all that hard to do.
From there, I just learned via QB threads, youtube videos and other things I read on the web.
Before all this, I had taken a couple of PP classes ... and they were disastrous!
I was sure it was a technique I would never come to like.
Now ... I love it!
It takes a bit of time to get your own rhythm and comfort with it ... and then you're away to the races!
Good Luck!
