Sew a sphere by stitching two fabric halves together, leaving a small opening to turn and stuff

A sphere plush is made by cutting two identical half-circle or circular fabric pieces, sewing them together with the right sides facing inward, turning the whole thing inside-out through a small opening, stuffing it with fiberfill, and closing the opening with a ladder stitch. The shape comes from the curve of the seam and the way the stuffing fills the space—no special pattern or shaping required beyond two matching pieces and careful stitching around the edge.

The whole project takes two to four hours depending on how large you make it and how comfortable you are with hand-sewing the final closure. You will need fabric (cotton, fleece, or minky all work), thread, fiberfill stuffing, a needle, scissors, pins, and a sewing machine or needle and thread for the entire seam.

Key Takeaways

  • Cut two identical circular or half-circle pieces from your fabric, making sure the edges are even so the seams line up when you sew them together.
  • Sew the two pieces together with right sides facing inward, leaving a 2-inch opening for turning and stuffing.
  • Turn the sphere inside-out through the opening, push out the seams gently with a blunt tool, and stuff firmly with fiberfill until it holds its round shape.
  • Close the opening with a ladder stitch, which hides the seam inside the plush and creates an invisible finish.
  • Sphere size depends on your fabric circle diameter—a 6-inch circle makes a small plush, a 10-inch circle makes a medium one.

Cutting two matching fabric circles

Start by deciding how large you want your finished sphere. A 6-inch diameter circle will yield a plush about the size of a tennis ball; a 10-inch circle makes one roughly the size of a grapefruit. Draw a circle on paper using a compass, a bowl, or a plate as a template, then cut it out and use it as your pattern.

Pin the paper pattern to your fabric and cut around it carefully with sharp scissors. Cut two identical circles—these will become the two halves of your sphere. Check that both pieces are the same size by laying them on top of each other; they should match exactly at the edges. If one is slightly larger, trim it to match the other.

Sewing the two halves together

Place the two fabric circles with right sides facing each other—the pretty side of the fabric should be on the inside, and the wrong side (the back) should face outward. Pin around the entire edge, spacing pins about 2 inches apart so the fabric does not shift while you sew.

Sew around the edge using a 1/4-inch seam allowance (the distance from the edge of the fabric to your stitch line). Start at any point and sew all the way around, but stop about 2 inches before you reach your starting point. This opening is where you will turn the sphere inside-out and stuff it. Backstitch at the beginning and end to lock the thread and prevent the seam from unraveling.

If you are hand-sewing instead of using a machine, use a running stitch or backstitch, keeping your stitches small and even—about 1/8 inch apart. The seam does not have to be perfect, but it should be tight enough that stuffing does not leak out later.

Turning and inspecting the seam

Reach through the 2-inch opening and grab the fabric on the opposite side, then pull the entire sphere inside-out through the hole. This takes a little patience—go slowly and do not force it, or you may tear the seam. Once it is turned, the right side of the fabric is now on the outside and the seam is hidden inside.

Use a blunt tool like a chopstick, the eraser end of a pencil, or a point turner to gently push out the seams from the inside, especially along the curved edges. This makes the sphere look rounder and more finished. Do not poke so hard that you puncture the fabric.

Stuffing the sphere firmly

Pull off small pieces of fiberfill—about the size of a grape—and push them through the opening one at a time using your fingers or a chopstick. Pack the stuffing firmly so the sphere holds its shape and feels solid, but do not overstuff so much that the seams strain or the fabric looks lumpy. A sphere the size of a grapefruit typically needs about one to two cups of fiberfill.

As you stuff, rotate the sphere and feel it from all sides to make sure the stuffing is even. If one spot feels thin, add more stuffing there. The goal is a plush that feels like a firm pillow, not a floppy bag.

Closing the opening with a ladder stitch

Thread a needle with thread that matches your fabric. Fold the raw edges of the opening inward about 1/4 inch and pin them closed so they line up neatly. This creates a clean edge to stitch.

Use a ladder stitch (also called a whip stitch or invisible stitch) to close the opening. Bring the needle up through one folded edge from the inside, then cross over and insert it into the opposite folded edge, sliding the needle inside the fold for about 1/4 inch before bringing it back out. Cross back to the first side and repeat, moving along the opening. The thread runs inside the fold of fabric, so it stays hidden. After every three or four stitches, gently pull the thread to draw the opening closed.

Once you reach the end of the opening, tie off the thread inside the plush by making a small knot, then run the needle through the stuffing for an inch or so before bringing it back out and cutting the thread. This hides the knot inside the plush.

Common mistakes and how to avoid them

The most common error is leaving the opening too small—if it is smaller than 1.5 inches, turning the sphere inside-out becomes very difficult. Aim for 2 to 2.5 inches. Another mistake is not leaving enough seam allowance; if you sew right at the edge of the fabric, the seam will fray and stuffing may leak out. Always use at least a 1/4-inch seam allowance.

Uneven stuffing creates a lumpy, misshapen plush. Take time to feel the sphere as you stuff and add more where needed. Finally, a sloppy ladder stitch is visible from the outside. Keep your stitches small (about 1/8 inch) and pull the thread gently but firmly after every few stitches so the opening closes neatly without puckering.

Frequently Asked Questions

What fabric works best for a sphere plush?

Cotton, fleece, and minky are all good choices. Cotton is affordable and straightforward to sew; fleece is soft and forgiving if your stitches are not perfect; minky is luxuriously plush but can be slippery to cut and sew. Avoid stretchy knits unless you have experience with them, as they require special needles and techniques.

Can I make a sphere without a sewing machine?

Yes. Hand-sewing takes longer—expect three to four hours instead of two—but the process is the same. Use a backstitch or running stitch, keep your stitches small and even, and take breaks to avoid hand fatigue. The final ladder stitch is hand-sewn regardless, so you will already be comfortable with that part.

How do I make the sphere perfectly round?

Stuff it evenly and firmly, rotating it often as you add fiberfill. A sphere is naturally round if the stuffing is distributed evenly throughout. If it looks lopsided after you close it, you can carefully open a small section of the ladder stitch, add or remove stuffing as needed, and re-stitch it closed.

What size opening do I need to leave for turning and stuffing?

Leave 2 to 2.5 inches. This is large enough to turn the sphere inside-out without tearing the seam and wide enough to stuff comfortably. If you leave less than 1.5 inches, turning becomes very difficult and you risk ripping the fabric.

Can I add details like eyes or a mouth after stuffing?

Yes. Once the sphere is complete and the opening is closed, you can hand-sew on buttons for eyes, embroider a mouth, or glue on felt shapes. Sew buttons through the fabric and stuffing so they are find, or use a strong fabric glue for felt pieces. Let any glue dry completely before handling the plush.
