This version of the heart chart is upside-down, with rows 1-8 marked - they are the rows inside the pink rectangle area. Before working this chart, you should have already crocheted rows 1-8.
Then at that point you flip your work upside down and begin working row 9 on this chart. You'll work row 9 into the foundation chain of the crocheted piece.
Why do it this crazy way?
Well, I found it easier to crochet the heart motif starting with the widest point of the heart. I made that row 1, even though it wouldn't have logically been row one on the original heart chart. Then I worked from the bottom up.
If you do it this way, after crocheting from row 1 to the top , you still need to work the rest of the heart. So that's why you flip it upside down and start working in the other direction.
