Realistic Crochet Heart Pattern

Realistic Crochet Heart Pattern

Today, I’m sharing with you a crochet heart pattern, but not just any crochet heart. This one isn’t the cutesy Valentine heart you might be used to seeing, but I think this realistic crochet heart pattern is a lot more interesting and fun to make. I made this for my dad last year after he underwent major heart surgery, and it was a big hit! You guys asked for the pattern and I even had requests for custom orders, so here it is!

When I made this, it was a pretty rough time for my family. My dad, who had had a major bypass surgery ten years ago, was in the hospital again for another heart procedure. He’s a doctor himself so I thought something fun like this might lighten the mood.

Although I couldn’t get every single structure of the heart in this model, my dad was so excited about this simple plushie. He would take it out to show everyone who visited him and he’d explain his procedure to them using this as a model.

The crochet heart pattern is a lot simpler than you would expect just by looking at it. I worked each piece as a simple shape and then sewed it all together into the final shape. For the veins and arteries, I used blue and red yarn to make big stitches across the body of the heart. I wasn’t too precise about getting them in the right places, but I checked a diagram from a biology textbook to make sure I got the most important ones right.

To make this crochet heart pattern, we’re going to start with the actual heart muscle and then add on all the other parts and veins to make it look realistic.

Assembly:

Now that all the pieces are done, it’s time to assemble the crochet heart pattern! First, lightly add stuffing to all of three of the larger tubes, but keep it mostly in the center so it doesn’t stick out the ends.

Next, attach the superior vena cava (the blue tube with a bulge in the middle) to the side of the heart, sewing along the sides where the two touch.

Then sew the right atrium (triangle) over the end of the SVC. As you work around, add a little bit of stuffing into the gaps to give it more depth.

Now, sew the three small red tubes to the center of the aorta (big red tube) and bend the tube so it’s curved. Sew one end of the curved tube to the top of the heart, slightly closer to the SVC than the center.

Sew the two small blue tubes onto the end of the pulmonary artery. Then, position the artery NEXT TO the curve of the aorta, and the end just behind the SVC. Sew it into place at the top of the heart, then continue sewing around the tube, attaching the aorta to it. Basically, make the curve of the aorta sewn in place, but leave the end unattached.

Finally, use extra yarn and your tapestry needle to embroider on the veins on the heart to make it more realistic (I just guessed where they should go). And then you’re done! If you like, you can also use this crochet heart pattern and use only different shades of red and dark purple to make it even more realistic.

And you’re done!

I think one of my favorite things about crocheting is being able to create things like this crochet heart pattern. It was random and spur of the moment, but the fact that I can use string to make something special and specific is amazing to me. My dad loves this and it feels amazing to have been able to say I made it for him.

I hope you all enjoyed this pattern! I’ll be back with more soon, but in the meantime, why not check out some of my favorite knitting and crochet books?

Thank you, Julie! It was a lot of fun trying to get it right and I had all the doctors and almost-doctors in my family pitching in!

Hey! I really love the pattern!! It is actually the first thing ever (apart from granny squares) that I am crocheting! I just have one question - for the main heart part, there is no row 17. Should I just do 18 and 19 (SC around) or should there be 3 rows of SC around? Thanks!!!

Hi Kathryn,

Thank so much! It's always fun trying something a little different. The row 17 isn't missing, it was just a typo! Just continue on to row 18 as normal. I'll fix the typo so there's no confusion later. Thanks for pointing it out :)

You have such a talent for crochet! It's great that your dad is doing better after his latest procedure. We all need to be more heart health conscious. Thanks for sharing at Snickerdoodle. Pinning.

Thank you, Beverly! We absolutely do, and we need to be aware of these things before something happens. We all learn about heart health in school, but no one thinks it could affect them until it does.
