Sewing lace requires slower speeds, stabilizing techniques, and needles designed for delicate work—the opposite of what works for cotton or denim.
Lace tears easily because the threads are thin and widely spaced, and heat from a fast needle can melt synthetic lace. The standard approach is to use a size 60 or 70 needle (the smallest common sizes), reduce your machine speed to 60 percent of normal, and stabilize the lace with tissue paper or a water-soluble stabilizer underneath. Most home sewers find that hand-sewing the first seam on a lace garment, or using a walking foot instead of a regular presser foot, prevents the puckering that happens when the feed dogs pull the delicate fabric unevenly.
The specific technique depends on what you are sewing—a seam, an appliqué, or an edge finish—and what kind of lace you have. Chantilly lace (with a solid design on a net background) behaves differently from Alençon lace (with a corded outline). This guide covers the most common situations: joining two pieces of lace, attaching lace to a stable fabric like cotton, and finishing a lace edge without a raw edge showing.
Key Takeaways
- Use a size 60 or 70 needle and reduce machine speed to 60 percent to prevent the needle from catching and tearing the delicate threads.
- Place tissue paper or water-soluble stabilizer under the lace to prevent puckering and keep the feed dogs from pulling the fabric unevenly.
- A walking foot feeds lace more evenly than a standard presser foot and is worth buying if you plan to sew lace regularly.
- Lace seams hold better when you sew slowly by hand for the first inch, then switch to the machine once the seam is anchored.
- Trim seam allowances to one-quarter inch after sewing to reduce bulk and prevent the seams from showing through the sheer fabric.
Choosing the Right Needle and Thread
A size 60 or 70 needle has a smaller eye and a thinner shaft than standard needles, which means it pierces lace without enlarging the holes or catching on the threads. Size 80 exists but is fragile and breaks easily on home machines. Size 70 is the practical minimum for most sewers. The needle type matters as much as the size: use a universal needle for natural-fiber lace like cotton or linen lace, and a ballpoint or stretch needle for synthetic lace (polyester or nylon), because the rounded tip slides between fibers instead of piercing them.
Thread weight should match the needle. Use size 50 or 60 thread (the thinner sizes) so the thread does not bulk up in the tiny needle eye. Polyester thread is more forgiving than cotton on delicate fabrics because it has slight give and does not snap as easily if tension is slightly off. If you are sewing white or cream lace, use white or cream thread; on darker lace, match the thread to the lace color, not the garment underneath. The thread will show through the sheer areas, so visibility matters.
Stabilizing Lace to Prevent Puckering
Lace puckers when the feed dogs pull the fabric unevenly, which happens because the open weave offers little resistance. The fix is to place a layer of support underneath the lace as you sew. Tissue paper is the cheapest option: tear a strip slightly wider than your seam allowance and pin it under the lace before you sew. After sewing, tear the tissue away—it comes off easily and leaves no residue. This method works for any lace and costs almost nothing.
Water-soluble stabilizer (also called wash-away stabilizer) is the alternative if you want to avoid tearing tissue paper away later. Pin it under the lace the same way, sew normally, then rinse the garment in cool water and the stabilizer dissolves. It is more expensive than tissue but leaves no paper fragments behind. For very delicate lace, use tear-away stabilizer on top of the lace as well as underneath—this sandwiches the lace and prevents the needle from snagging the threads as it enters and exits.
Machine Settings and Speed Control
Set your machine to a straight stitch (not zigzag) and reduce the speed to 60 percent of what you normally use. On most machines, this means turning the speed dial down or, on computerized machines, pressing the slow-speed button. The slower speed gives the needle time to pierce the fabric cleanly without heat buildup, which can melt synthetic lace. Test the speed on a scrap of the same lace before you sew the actual garment.
Reduce the presser foot pressure to the lowest setting that still feeds the fabric. High pressure flattens the lace and can distort the pattern. If your machine has a pressure dial, start at 1 or 2 out of 10. If it does not have a dial, you cannot adjust it, but a walking foot (also called an even-feed foot) solves the problem by feeding the top and bottom layers at the same rate. A walking foot costs $20 to $50 depending on your machine brand, but it is the single best investment for sewing lace regularly.
Sewing Lace-to-Lace Seams
When you join two pieces of lace together, the seam is visible from both sides, so the stitching must be straight and even. Pin the two pieces with the right sides together, matching the pattern if the lace has a directional design. Place tissue paper under both pieces. Hand-sew the first inch of the seam using a needle and thread that matches the lace—use a backstitch (the strongest hand stitch) and make stitches about one-eighth inch long. This anchors the seam so the machine does not shift the fabric when you start.
Switch to the machine and sew slowly along the seam line, removing pins as you approach them. Stop every inch or so and check that the stitching is straight and the lace is not puckering. If it is puckering, stop, pull out the stitches, adjust the stabilizer or presser foot pressure, and try again. After sewing the entire seam, trim the seam allowance to one-quarter inch on both sides using small scissors or a seam ripper. This narrow allowance prevents the seam from showing through the sheer lace and reduces bulk.
Attaching Lace to Stable Fabric
When you sew lace to cotton, silk, or another stable fabric, the seam is usually hidden on the inside of the garment, so the technique is less fussy. Pin the lace to the stable fabric with right sides together, place tissue paper under the lace only (not under the stable fabric), and sew at your reduced speed. The stable fabric underneath supports the lace and prevents most puckering on its own.
After sewing, trim the lace seam allowance to one-quarter inch and the stable fabric allowance to one-half inch. Press the seam toward the stable fabric side (not toward the lace), using a low heat setting if the lace is synthetic. If the seam allowance shows through the lace from the front, cover it with a narrow strip of matching lace or a bias tape in a matching color, sewn down by hand or machine. This finish is called a French seam variation and is standard in lace garment construction.
Finishing Lace Edges Without Fraying
Lace edges do not fray the way woven fabric does, but the cut edge looks unfinished. The simplest finish is a narrow zigzag stitch sewn along the edge: set your machine to a narrow zigzag (width 1.5 to 2, length 1.5), reduce the speed, and sew along the cut edge with the lace stabilized underneath. The zigzag catches the threads and prevents them from pulling loose. This works on any lace and takes only a few minutes.
A more polished finish is a rolled hem, which folds the edge under and stitches it down so no raw edge shows. This is slower and requires practice, but it is the standard finish on fine lace garments. Fold the edge under one-eighth inch, press it lightly with a cool iron, then fold it under again and press. Sew the fold down by hand using a slip stitch (a stitch that runs inside the fold and is nearly invisible from the outside) or by machine using a narrow zigzag. For a quicker version, use a bias tape in a matching color: fold the tape over the edge, pin it, and sew it down by hand or machine.
Common Mistakes and How to Avoid Them
The most common mistake is using a needle that is too large, which enlarges the holes in the lace and makes the stitching visible and weak. If your stitching looks loose or the lace tears as you sew, switch to a size 70 needle when ready. The second mistake is sewing too fast, which causes the needle to catch and skip stitches. If you see skipped stitches, slow down further and check that the needle is inserted correctly (the flat side of the needle faces the right direction for your machine—check your manual).
The third mistake is not stabilizing the lace, which leads to puckering that cannot be pressed out. If you see puckering after sewing, you cannot fix it by pressing; you have to pull out the stitches and resew with stabilizer underneath. The fourth mistake is using thick thread or high presser foot pressure, both of which distort the lace pattern. Use thin thread (size 50 or 60) and the lowest pressure your machine allows. The fifth mistake is pressing lace with high heat, which can melt synthetic lace or flatten the texture of natural lace. Always use a low heat setting and press from the back of the garment, not the front.
Frequently Asked Questions
Can I use a regular needle on lace?
A size 80 or 90 needle will work in a pinch, but the stitching will be loose and visible, and the lace may tear. Size 70 is the practical minimum. If you are sewing lace regularly, buy a pack of size 70 needles—they cost a few dollars and make a noticeable difference in the finished seam.
What if my lace keeps puckering even with stabilizer?
Check three things: the needle size (switch to 70 if you are using 80 or larger), the presser foot pressure (lower it as much as possible), and the stabilizer placement (make sure it is under the lace, not just pinned loosely). If puckering persists, try a walking foot, which solves the problem on most machines.
Do I have to hand-sew the first inch of a lace seam?
No, but it helps. Hand-sewing anchors the seam so the machine does not shift the fabric when you start, which reduces puckering. If you are confident with your machine and have a walking foot, you can sew the entire seam by machine. Test on a scrap first.
Can I use a zigzag stitch to sew lace seams?
A zigzag is weaker than a straight stitch and shows more on delicate lace. Use a straight stitch for seams. A narrow zigzag is fine for finishing edges, where strength is less critical.
What thread should I use on dark lace?
Match the thread color to the lace, not the garment underneath. The thread will show through the sheer areas, so a mismatch is visible. If the lace is a color you cannot find thread for, use a neutral gray or taupe, which blends into most lace colors.
