Materials You'll Need

Alright, before we get started, let's gather our supplies. Having everything ready will make the sewing process a breeze. Here's what you'll need to make your Companion Cube: We will cover everything you need. You'll want to get all of this stuff together before we start to make your life easier.

Fabric: The primary material for your cube. You'll want to choose a fabric that's easy to work with and holds its shape well. Felt is a great option because it's available in many colors, doesn't fray easily, and is relatively easy to cut and sew. Consider using a medium-weight felt. For the cube's main body, you'll want a light gray or off-white color. You'll need enough fabric to cut out six squares for the cube's sides. Remember to measure your fabric and cube size to ensure you have enough fabric to cover it. The type of felt you choose is up to you. You can even try using different types of materials to give your cube a unique look. The main thing is to pick a fabric that you enjoy working with and that will give you the look you want. Think about colors as well. The possibilities are endless!
Fabric for the Heart: This is where you can get creative! Red felt is the classic choice for the heart, but feel free to experiment with other colors or patterns. You will need a small amount of fabric. This will be a great way to add a bit of customization to your cube. Make sure that the heart is the appropriate size. It's best to have the heart a bit larger than you need so that you can cut it to the perfect size later. This part is a great opportunity to make the cube your own. Don't worry, even if you mess up you can always start again!
Stuffing: To give your cube its three-dimensional shape, you'll need something to stuff it with. Poly-fil is a popular choice because it's soft, lightweight, and easy to work with. You could also use other stuffing materials like cotton or scraps of fabric, but make sure your choice will give the cube a nice shape. This is an important step to remember. You can choose different types of stuffing to change the look of your cube. Make sure to pack the cube firmly to give it that cube look. Don't be afraid to put a lot of stuffing, but remember to be careful. Also, make sure that the cube is stuffed evenly.
Sewing Machine or Needle and Thread: You'll need a way to sew the fabric pieces together. A sewing machine will make the process much faster, but hand-sewing is also an option. If you're hand-sewing, make sure you have a good needle and strong thread. Also, remember to take your time and make sure that you do neat stitches.
Scissors or Rotary Cutter: For cutting the fabric. A rotary cutter can make cutting straight lines easier, but scissors will work just fine. Make sure your scissors are sharp, so that it's easier to cut through the material. If you have a rotary cutter, you can use it to speed up the process. Make sure to be safe when using these tools. Use caution!
Ruler or Measuring Tape: To measure and cut your fabric accurately. Accuracy is key when it comes to sewing, so make sure to take your time to be precise.
Pins: To hold the fabric pieces together while you sew. This will help you keep the pieces aligned and prevent them from shifting. Make sure you use enough pins to make sure the cube doesn't move around.
Pencil or Fabric Marker: For marking the fabric. This is very important. You can use this to mark the fabric, so you know where to cut, or sew. Make sure your mark is visible but won't be seen when the project is done.
Template (Optional): You can either draw your own template or find a free printable template online. This will help you get the right shape and size for your cube pieces and heart.

Cutting Out the Fabric Pieces

Now, let's get our hands dirty and start cutting! This is where we shape the Companion Cube and bring it to life. This is one of the most important parts of the project. Pay attention and you will be able to do this with no issues. Remember that accuracy is very important when it comes to cutting the pieces. Take your time, and measure everything twice to make sure it's accurate.

Cube Sides: Using your ruler and pencil or fabric marker, measure and cut out six squares of fabric for the cube's sides. The size of your squares will determine the overall size of your cube. A good starting point is about 6-8 inches per side. But feel free to adjust this based on your preference. Make sure that all the squares are the same size. If the sizes are incorrect, then the cube may not turn out correctly. Remember to use the right tools when cutting the fabric pieces.
Heart: If you're using a template, trace the heart shape onto your red fabric and cut it out. If you're drawing your own heart, make sure it's a good size for your cube. The heart should be large enough to be easily seen, but not so big that it overwhelms the cube. Also make sure the heart is the right shape. You should know how to draw a heart. Remember that the better the heart looks, the better the overall cube will be. It's important to make the heart look nice. Even if the heart is not perfect, it will look amazing anyway! Don't be afraid to try more than one time. This part is a great opportunity to make the cube your own!

Sewing the Cube Together

Time to sew! This is where you see your Companion Cube start to take shape. This step requires precision and attention to detail, but don't worry, it's totally achievable! Let's get started. Get ready to do some sewing! Remember to stay safe. If you're unsure, ask for help.

Attaching the Heart: Place the heart onto one of the cube's squares. Center it and pin it in place. Then, sew around the edges of the heart to attach it to the fabric. You can use a straight stitch or a decorative stitch, depending on the look you want. It's best to have the heart a bit larger than you need so that you can cut it to the perfect size later. Also, make sure that it's centered. This part is a great opportunity to make the cube your own. Also, make sure the heart doesn't move around when sewing, that's why you need to use pins. You should pin it to the square to make it easier to sew. Try to make it neat.
Sewing the Sides: With the heart-adorned square facing outwards, pin it to another square, right sides together. Sew along one edge, leaving a seam allowance (usually about ½ inch). Repeat this process, sewing the sides together to form a cube shape, but leave one side open for stuffing. Remember to make the seam allowance to make sure it looks nice. Also, make sure you align the edges of the fabric pieces.
Turning and Stuffing: Once you've sewn all the sides together (except for one), turn the cube right-side out through the open hole. Now, it's time to stuff your cube! Start filling it with the Poly-fil, making sure to push it into the corners to give the cube a nice, square shape. Don't overstuff it, or it will look lumpy. Remember to stuff the cube firmly to give it that cube look. Don't be afraid to put a lot of stuffing, but remember to be careful. Also, make sure that the cube is stuffed evenly.
Closing the Hole: Once the cube is stuffed to your liking, fold the edges of the open side inwards and pin them together. Sew the hole closed, either by hand or with your sewing machine. Make sure your stitches are neat and secure, so the stuffing doesn't come out. This will make your Companion Cube looks amazing! Make sure you sew it up nicely.

Finishing Touches and Customization

Congratulations! You've made your very own Companion Cube! But the fun doesn't have to stop there. This is your chance to add your own personal touches and make it truly unique. Here are a few ideas:

Embellishments: Consider adding extra details like embroidered lines or dots to give the cube a more detailed look. You can also sew on buttons or other small embellishments to give it character. Don't be afraid to get creative with it. This is your chance to shine!
Color Variations: Experiment with different colors of fabric for the cube's body and heart. You could create a rainbow cube or a cube with a unique heart design. Consider changing the colors of the fabric. You can also make more than one to display them!
Size: You can adjust the size of the cube to your liking. Make a giant one for your bed, or a mini one to keep at your desk. Make sure you use the appropriate size.
Fabric Choices: Try using different types of fabric. Try using different fabrics such as cotton or other materials. This will make the cube unique!

Tips and Tricks for Success

To ensure your Companion Cube turns out perfectly, here are a few extra tips and tricks:

Measure Twice, Cut Once: Always double-check your measurements before cutting the fabric to avoid mistakes. Remember, accuracy is very important when it comes to sewing, so make sure to take your time to be precise.
Use the Right Tools: Make sure you have the right tools for the job. Having the correct tools will make the whole process easier and faster.
Take Your Time: Sewing can be a relaxing activity. Don't rush the process, and take your time to ensure your stitches are neat and secure.
Iron Your Fabric: Before cutting and sewing, iron your fabric to remove any wrinkles and ensure accurate measurements. This will make the process much easier.
Practice Makes Perfect: If you're new to sewing, don't be discouraged if your first cube isn't perfect. Keep practicing, and you'll get better with each one. Don't be afraid to try more than one time. Sewing is all about having fun and letting your creativity shine.
