The Two Ways to Close a Pillow: Hand Sewing and Machine Stitching
You close a pillow by stitching the opening shut after you have stuffed it. The two main methods are hand sewing with a needle and thread, which takes 10 to 20 minutes and leaves almost no visible seam, and machine sewing, which takes 3 to 5 minutes but requires you to line up the fabric edges precisely. Hand sewing is the standard choice because the opening is usually on a side or corner where a machine cannot easily reach, and because hand stitches blend into the fabric better than machine stitches do.
Both methods use the same basic principle: you fold the raw edges of the opening inward so they are hidden, then stitch them together. The difference is the tool and the stitch pattern. This guide covers both, starting with hand sewing because it is the method most pillow makers use.
Key Takeaways
- Hand sewing a pillow closed uses a ladder stitch (also called a whip stitch), which hides the thread inside the fold of fabric and leaves almost no visible seam line.
- You must fold the raw edges of the opening inward by about half an inch on both sides before you begin stitching, so the folded edges meet in the middle.
- The needle travels inside the fold of fabric on one side, then crosses over to the fold on the other side, creating a seam that closes from the inside out.
- Machine sewing is faster but only works if your pillow opening is on a straight edge where the presser foot can reach; it leaves a visible stitch line on the outside.
- Test your thread color on a scrap of your pillow fabric first, because thread that matches perfectly on the spool may look wrong once it is stitched into the weave.
Prepare the Opening: Fold and Pin the Edges
Before you stitch, fold the raw edges of the opening inward by approximately half an inch on both sides. This fold hides the raw fabric and creates a clean seam line. Pinch the fold with your fingers first to see where it will sit, then use straight pins to hold it in place along the entire opening.
The two folded edges should meet in the middle of the opening, touching but not overlapping. If they overlap, your fold is too wide; if they do not touch, your fold is too narrow. Adjust and re-pin until the edges align. This step takes 2 to 3 minutes but prevents the seam from puckering or pulling as you stitch.
If your pillow fabric is slippery (silk, satin, or lightweight cotton), fold the edges and then press them with a hot iron for 10 seconds to set the crease. This keeps the fold from shifting as you work. Do not press if your fabric is synthetic or heat-sensitive; pinning alone is enough.
Hand Sewing: The Ladder Stitch for an Invisible Seam
Thread your needle with a length of thread about 18 inches long and tie a knot at one end. Match your thread color to the pillow fabric as closely as possible. Bring the needle up through the fold on one side of the opening, about a quarter inch from the corner. The knot will stay inside the fold and will not be visible.
Cross the needle straight across to the fold on the opposite side and insert it directly into the fold (not through the fabric face). Slide the needle inside the fold for about a quarter inch, then bring it back out. Pull the thread snug but not tight—tight enough that the seam closes, but loose enough that you can still see a tiny gap between the two folded edges.
Go back to the first side and repeat: insert the needle into the fold where you just came out, slide it a quarter inch inside the fold, and bring it back out. The thread should travel inside the fold on each side, crossing over the opening between stitches. This creates a seam that closes from the inside out, leaving almost no visible thread on the outside.
Continue this pattern all the way around the opening. Every 2 to 3 inches, pull the thread gently to close the gap a little more. When you reach the end, make two small stitches in the same spot to lock the thread, then slide the needle inside the fold for an inch and bring it back out. Trim the thread close to the fabric; the end will disappear inside the fold.
Machine Sewing: A Faster Option for Straight Edges
Machine sewing works only if your pillow opening is on a straight edge where the presser foot can reach without hitting a corner or seam. If your opening is on a side, you can machine stitch it. If it is on a corner or near a seam, hand sewing is your only option.
Fold the raw edges inward by half an inch on both sides, just as you would for hand sewing, and pin them in place. Set your machine to a straight stitch with a stitch length of 2.0 to 2.5 millimeters. This length is small enough to hold the seam but large enough to see and remove if you make a mistake.
Align the folded edges under the presser foot so the needle will stitch right along the fold line where the two edges meet. Sew slowly, keeping the edges even as you go. The stitches will be visible on the outside of the pillow, so this method is best for pillows where a visible seam line is acceptable or where the seam will be hidden (for example, a pillow that will sit against a wall).
Common Mistakes and How to Avoid Them
The most common mistake is folding the edges too far inward, so they overlap in the middle. This creates a thick, lumpy seam that is hard to stitch and looks uneven. Fold only half an inch on each side, and check that the edges meet but do not overlap before you pin.
The second mistake is pulling the thread too tight as you hand stitch. Tight stitches pucker the fabric and can tear it. Pull just enough to close the gap; the seam should feel firm but not strained. If you see wrinkles forming around the seam, you are pulling too hard.
The third mistake is using thread that does not match the fabric. Test your thread on a scrap of pillow fabric first. Thread that looks like a perfect match on the spool often looks wrong once it is stitched into the weave. If you cannot find an exact match, choose a thread one shade darker rather than lighter; it will blend better.
For machine sewing, the most common mistake is not folding the edges far enough inward, so raw fabric is still visible at the seam line. Fold a full half inch and press it with an iron to set the crease before you sew.
Reinforcing the Seam for Pillows That Get Heavy Use
If your pillow will be sat on, thrown around, or washed frequently, reinforce the seam by stitching over it a second time. For hand sewing, go back along the same seam line with a second row of ladder stitches, offset by about an eighth inch from the first row. This doubles the strength without making the seam noticeably thicker.
For machine sewing, stitch a second line parallel to the first, about a quarter inch away. This creates a box-like seam that distributes stress across a wider area. The second line of stitches will be visible, so only do this if your pillow design allows for a decorative double seam.
Finishing Touches and When to Trim Threads
Once you have stitched the entire opening closed, trim any loose thread ends with scissors. For hand-sewn seams, trim the thread flush with the fabric; the end will disappear inside the fold. For machine-sewn seams, trim the thread tails at the beginning and end of the seam to about a quarter inch.
If you see any gaps in the seam after you have finished, you can go back and add a few more stitches to close them. This is normal and takes only a minute. Once the seam is complete, gently squeeze the pillow to make sure the stuffing is distributed evenly and the seam feels solid.
Frequently Asked Questions
Can I machine sew a pillow closed if the opening is on a corner?
No. The presser foot cannot navigate a corner without bunching the fabric or breaking the needle. If your opening is on a corner, use hand sewing instead. If you must use a machine, reposition the opening to a straight edge before you stuff the pillow.
What thread should I use to sew a pillow closed?
Use all-purpose polyester or cotton thread that matches your pillow fabric as closely as possible. Test the color on a scrap first. For decorative pillows where the seam will be visible, you can use contrasting thread for a design effect, but for most pillows, matching thread is the standard choice.
How tight should I pull the thread when hand sewing?
Pull just tight enough to close the gap between the folded edges. The seam should feel firm but not strained. If you see wrinkles or puckering around the seam, you are pulling too hard. A good test is to pull until the gap closes, then release slightly—that is the right tension.
Can I sew a pillow closed if I have never sewn before?
Yes. Hand sewing a pillow closed is one of the easiest sewing projects because the stitches do not have to be perfect—they are hidden inside the fold. Practice on a scrap of fabric first to get the feel of the ladder stitch, then move to your pillow. Most beginners finish their first pillow in 15 to 20 minutes.
What do I do if my thread breaks while I am sewing?
Tie a knot at the end of the remaining thread and continue sewing from that point. Once you have finished the seam, go back and stitch over the gap where the thread broke. You can also prevent breakage by using a shorter length of thread (about 18 inches) and rethreading more often rather than using one very long piece.
