How to Make an Aperture Laboratories Personality Core Plush (Part 3)

Introduction:

We’re almost there! Today, we’ll be finishing up our personality core: attaching the handles, finishing and stuffing the sphere, and stitching on the final decorations. If you missed part two, you can find it here.

Let’s begin:

Grab the handles you sewed and stuffed earlier, the part of the sphere we created last time, and a length of black thread. We’re going to attach the black cylinder to the edge of the side sphere panel, as shown below.

But first, we’re going to need to cut out a hole where you want to attach the handle. The circle should be no wider than about 3/4s of an inch across. It’s fairly hard to predict just how big our circle will be when using the method laid out below, so cut it small at first and only make it bigger if you need to.

Find the place which will be the center of your circle, and fold the material over so that your center point is at the corner of the folded felt, as shown above.

IMG_1365

Cut the corner in a curve. The result will be something like this:

By folding the sphere in half, we can find the exact place where we need to cut out a symmetrical circle on the other side of the optic. We’ll also need to cut two of these circles below the optic for the lower handle.

Remember, the holes need to be on the same level so that the handle won’t be crooked.

I cut the holes a little too big. Learn from my mistakes, and cut your holes small at first. Only make them bigger if you really need to! You can stitch the black cylinders into holes that are a bit too big, but it will stretch and pucker the fabric around them, resulting in an ugly finish.

Sew in the black cylinders, using a length of black thread and a blanket stitch. At the end, when you’ve stitch both, you should have something like this:

IMG_1371

Now, stitch in the lower handle in the same way.

IMG_1373

Here’s how it looks inside:

IMG_1374

You can see some of the puckering around the black cylinders. Oops…

Now, it’s time to finish the sphere itself, and stuff it. Grab the last two sphere panels and a length of white thread.

IMG_1317

You know how to do this by now. Starting at the top, blanket stitch the panels together down the curved side, until you get to the bottom.

IMG_1321

Grab the other panel and stitch it to the raw edge of the other side of the sphere. And… you’re finished with the basic sphere! (Finally, after like three posts worth of this…) It should look something like this:

Sphere Finished

Now, it’s time to turn the sphere inside out and stitch up the back.

IMG_1375

Starting at the bottom, grab another length of white thread and, once more using a blanket stitch, sew up the seam about a fourth of the way. Then, tie off the thread. We need to leave a gap of several inches so that we can pull the handles through and turn the core right side out.

IMG_1376

Snip the thread and tie another knot at the end. Starting at the top, stitch up the seam, leaving about a three inch gap un-sewed.

IMG_1377

Reach through the gap, grab one of the handles, and pull it through. You’ll have to bend it, but that’s fine. If it’s stuffed firmly, as it should be, you’ll be able to just press it back into shape later on. Anyway, pull one handle through, then the other, and turn the whole thing right side out. Now, it’s time to stuff your core!

IMG_1381

Don’t skimp on this step. You want your core to be fairly firm, so he holds his shape when you give him a great big hug! (And he is supposed to be a robot made of metal, after all…) Also, make sure you stuff the black cylinders so that the handles aren’t floppy.

Stuffed Core

Alright! Now it’s time to stitch up that gaping hole at the back. Get a length of white thread, knot the end, and get ready to make a hidden stitch. This special stitch of my own devising is designed to mimic the back-and-forth loops of a right-side-out blanket stitch, but sewed from the outside.

IMG_1384

Pass the needle through one of the raw edges of the felt. Pull it through, and loop back over, making another stitch through the edge of the other panel. You want to fold the raw edge over slightly. Below, I’ve illustrated the steps of this stitch with a few photos.

Hidden Stitch

This stitch fairly difficult to master, and even more difficult to explain properly. The end result should be that the raw edges of the panels are tucked underneath the seam, invisible to any prying eyes. 😛 If you can’t get the hang of this stitch, that’s fine. Just use a simple whip stitch. Even if the result is a bit ugly, it’s fine. We’ll be covering it up with the core’s back port in just a few minutes. When you reach the end of the gap, tie off the thread.

IMG_1391

We are almost done, and we’re completely through with any stuffing or blanket stitching. Now, it’s time to stitch together the back port, and attach it to the sphere.

IMG_1392

Grab the other 4 inch black circle, the gray circle with a cross cut out, and the 1 inch gray circle. Stitch them together as shown below:

Back Port

We’re going to attach this port to the back of the sphere, right over the seam we just stitched up.

IMG_1395

Place the port in the center of the back of the sphere. Grab a needle and a length of black thread, and, beginning at the bottom of the circle, on the seam line, make a stitch. Sew it on  all the way around, as shown below:

Back Stitch

Here’s what it should look like when it’s stitched on:

IMG_1410

The top and bottom of our core are looking a bit empty… Grab the two 4 inch gray rectangles, and the 2 ½ inch black rectangles. Stitch them together as shown below:

Top and Bottom peices

These will be stitched onto the top and bottom of the sphere. Use the same method we used earlier for the back port to attach them, this time with a length of gray thread.

IMG_1417

Stitch one on top and one on bottom.

Now, grab some black thread and the four long black accent strips and get ready to attach them. When sewn on, they will look like this:

IMG_1421

You’ll need two for the top and two for the bottom of the sphere. They pass above the black handle pieces, and are stitched to the edges of the 4 inch black circles at the front and back of the core. Attach them to the black circles as shown below.

IMG_1422

We’ll just be using a simple whip stitch. One stitch through, then back over and through again, till you get to the end of the short edge of the strip.

IMG_1423

Attach the other end of the strip to the black circle at the back of the sphere. It should be flush with the sphere, and look like this:

IMG_1425

Stitch another strip in the same way on the other side of the optic, then turn the core over and do the same at the bottom with the other two strips. Depending on how spherical your core turned out, you may have to trim the strips so that they fit.

IMG_1428

There you go! We’re almost done. Just one more little thing to finish off…

IMG_1430

Grab the last two pieces, the 3 inch by 2 inch black rectangles, and a length of black thread. We’ll stitch these over the center of the white handle bars, to add some definition.

IMG_1433

Wrap one of the rectangles around the white tube, right at the center. The 3 inch sides should be the ones that you’re stitching together. Make sure that the rectangle is centered before you begin. Stitch up the side with a whip stitch, as shown below:

Handle Accent

You should pass the needle through the white fabric of the handle bar for a couple of stitches, so that you fix the black accent in place.

In the end, it should look like this:

IMG_1438

And… there you have it! You’ve completed your very own Aperture Laboratories Personality Core plush! Give him a big hug, just to let him know that you love him to bits, and go show him off to all your geeky friends. 😛

Here are a few more pictures of my Space Core:

Look how happy he is! Don’t you just wanna give him a great big hug??? ❤

How to properly care for your Personality Core:

The stuffing I use is supposedly machine washable, and, if you double thread all your needles, the plush *should* be strong enough to withstand a gentle machine washing. However, felt does get annoying little pills of fiber on its surface when machine washed, so I usually don’t wash any of my felt creations this way. If you really need to clean a spot or two off your personality core, use a damp washcloth to scrub it away.

(Note: The Enrichment Center makes no guarantees regarding the ability of an Aperture Laboratories Personality Core to survive machine washing, floods, lightning strikes, incineration, the Apocalypse, or any other unspecified catastrophic events. In the event that any of the above happen, you are on your own. However, we are pleased to let you know that all Aperture Science Personality Constructs will remain completely functional in low power, apocalyptic situations of as little as 1.1 volts. Good luck, test subject!)

Always show your personality core how much you care about him! A few hugs, cuddles, or words of endearment to this little robotic companion of yours will go a long way to keeping him happy, and stable. Do not, under any circumstances, attach your core to the Aperture mainframe or use him to replace a damaged central system core, as this will probably cause him to go completely power mad and try to kill you and/or throw you into dangerous testing situations once he assumes complete control of the facility. This has happened before. Once. Don’t do it. You will die.

Anyway, yay! We made it! Here is celebratory digital cake: 🎂🎂🎂


Thanks so much for bearing with me for this long haul. I hope you enjoyed this tutorial. If you make a personality core using this tutorial, please take a picture and tag me on Instagram (or Twitter). I’d love to see what you make! You can find me @ariaemaher on both platforms.

On the other hand, if you’re not a huge fan of Portal, and would like to see me make something from another game or fandom, please let me know! Send me your plush ideas, and I’ll definitely see what I can do… Also, let me know if there are any improvements I could make on this tutorial, or anything which could be better explained. I know explaining how to sew something is hard, so hopefully all the pictures will help you.

Anyway, bye for now!

🙂

  1. Well done! Nice pictures and clear instructions. You deserve some cake. One feels slightly intimidated by your near perfect needlework. I think I prefer the sewing machine.
