yes, trivia42. you are definitely making it too hard.
HOWEVER, i would bet a nice pile of cash that just about everybody does that the first (or first few, or first several) times they take a stab at paper piecing.
you attach the scraps of fabric to the pattern foundation in the order shown by the numbers.
all the fabrics go on top, so all the seams are sewn from the back.
i recommend you go to YouTube. search on paper piecing tutorials.
after watching one or a few i think you'll have a good enough understanding of the process to make this heart and be very pleased with your results.
