Two hearts as one by Martha Ess

I've been working on the pattern - Two hearts as one my Martha Ess. I have tried it in the past and got totally confused by all of the directions to pass shuttles in and out of rings, don't close ring, etc..

So I decided to do the hearts one at a time and it finally clicked while working on the second heart. I'm so happy. I am going to finish the individual hearts to have them as reference and will work on the combined hearts as soon as I get done.

Here is the picture of Martha's heart.
