Although I'm still pretty new to quilting, I think I can answer this question
: When you do PP, you use a paper base and then sew your fabric onto it BY MACHINE. EPP is a little different. My GFG (see Avatar) was done that way: I cut out the hexagons from paper and then basted the fabric onto them so that I got a hexagon with a "paper heart" (you could do that with other shapes, too). Those hexagons are then connected to each other BY HAND.
