07Sewing Together
Begin by sewing on the Vena Cava on the back. One should be facing down (towards Rnd 1 from the Main Body) and one should be facing up (towards the decreases).
Next sew on the Aortic Arch on the left side (Vena Cava are sewn on the back), stuff slightly, and then sew the other side onto the right side. Make sure it’s slightly tilting back.
Now sew on the Pulminary Arch to the right (and slightly up) from the Aortic Arch using the Chs from before Rnd 1 of the Pulminary Arch. Tuck the other end of the Pulminary Arch under the Aortic Arch.
Finally sew on the Pulminary Veins directly next to eachother on the right side (next to where you’ve sewn on the right side of the Aortic Arch).
To finish the heart up embroider on veins using Pink and Blue thread (or split yarn)
