This is the most scientifically accurate heart pattern on Etsy and Ravelry. You will be crocheting all of the visible parts of a human heart. You will make the main heart muscle, Inferior Vena Cava, Right Atrium, Superior Vena Cava, Aorta and Aortic Veins, Pulmonary Artery, Pulmonary Veins and the Left Atrium. This is a scientifically accurate size of the heart of an infant human. Works up nicely lots and lots of pictures plus a sewing guide to make sure your heart comes out great too. Great gift for a cardiologist, or someone working on their physical fitness. A great classroom aid for teaching children anatomy. I am a science teacher and pride myself on easy to read highly accurate patterns. Thank you for your purchase!

Inexpensive short pattern, only 4.00!
