What Crinoline Is and Why You Sew It
Crinoline is a stiff fabric made from cotton or synthetic fibers, often with a wire or plastic core running through it. You sew it into garments—usually skirts, petticoats, or the hems of formal dresses—to make fabric stand out and hold its shape. Unlike regular fabric, crinoline doesn't drape; it props itself up, which is why it's essential for ball gowns, 1950s-style skirts, and historical costumes.
Sewing crinoline differs from sewing regular cotton or linen because the material is rigid and can fray easily. The wire or plastic strips inside it can also shift during sewing if you don't anchor them properly. Learning the right technique saves you from puckered seams, broken needles, and crinoline that bunches up inside your garment.
Key Takeaways
- Crinoline has a wire or plastic core that runs in rows; you must sew along these rows to keep the structure intact and prevent the core from shifting.
- Use a size 90/14 or 100/16 needle and a walking foot on your machine to feed the stiff fabric evenly without puckering.
- Sew crinoline to the inside of a garment (usually the hem area) with the stiff side facing outward, using a 1/2-inch seam allowance.
- Backstitch at the start and end of every seam to lock the stitches, because crinoline's stiffness can cause thread to pull loose.
- Test your machine settings on a scrap of crinoline before sewing your actual garment to avoid needle breaks and tension problems.
Preparing Your Machine and Supplies
Start by changing your needle. A standard size 80/12 needle will break or bend when it hits the wire core in crinoline. Use a size 90/14 or 100/16 needle instead—these are thicker and designed for heavy fabrics. If you're sewing multiple layers (crinoline plus fashion fabric), go up to a 100/16.
Attach a walking foot to your sewing machine. This foot feeds both the top and bottom layers of fabric at the same speed, which prevents the stiff crinoline from bunching or puckering. If your machine doesn't have a walking foot, you can buy one at any fabric store for $15 to $40—it's worth the investment for this project.
Set your machine to a straight stitch with a stitch length of 2.5 to 3 millimeters. Crinoline is thick, so a longer stitch prevents the thread from breaking. Test these settings on a scrap of crinoline first. Sew a few inches, then pull gently on the thread to make sure it doesn't snap. If it does, loosen the top tension slightly and test again.
Cutting and Marking the Crinoline
Lay your crinoline flat on a cutting table and look at it closely. You'll see rows of wire or plastic running horizontally across the fabric—these are the support channels. You must sew along these channels, not across them, to keep the structure from collapsing.
Measure the circumference of the hem or area where you're attaching the crinoline. Add 1 inch for seam allowances. Cut your crinoline strip to that length and to the width you need (usually 2 to 4 inches for a petticoat hem, or whatever your pattern calls for). Use sharp fabric scissors or a rotary cutter—dull blades will crush the material and create frayed edges.
Mark the seam line with a fabric pencil or chalk. Draw a line 1/2 inch from the top edge of the crinoline strip. This is where you'll sew the crinoline to your garment. Mark the bottom edge as well so you know where to stop stitching.
Sewing Crinoline to Your Garment
Pin the crinoline to the inside of your garment (the wrong side of the fashion fabric) with the marked seam line aligned to the hem edge. The stiff side of the crinoline should face outward, away from the garment body. Use plenty of pins—at least one every 2 inches—because crinoline can shift as you sew.
Position the garment under the presser foot so the walking foot sits on top of the crinoline. Lower the presser foot and backstitch three or four stitches to lock the thread. Then sew forward along your marked line at a steady pace. Do not pull the fabric; let the walking foot do the work. Pulling can break the needle or cause the wire to bend.
When you reach the end of the seam, backstitch three or four stitches again to lock the thread. This is critical with crinoline because the stiffness of the material can cause regular stitches to pop loose over time. Trim any loose threads with scissors.
Sewing Along the Support Channels
Once the crinoline is attached to your garment, you need to stitch along each horizontal support channel to keep the wire from shifting. This is called channel stitching. Start at one end of the crinoline and sew a straight line along the first channel, backstitching at both ends.
Move to the next channel and repeat. Space your stitches evenly—usually one stitch line every 1 to 2 inches, depending on how much structure you want. The more you stitch, the stiffer the crinoline will be. For a full ball gown, stitch every channel. For a light petticoat, you can skip every other channel.
Keep the walking foot on for all channel stitching. The crinoline will want to bunch as you sew, and the walking foot prevents this. If you notice puckering, stop, remove the pins, smooth the fabric flat, and repin before continuing.
Finishing the Edges
After all seams are sewn, trim the bottom edge of the crinoline so it's even and doesn't stick out below the hem of your garment. Use sharp scissors or a rotary cutter. The crinoline should end just inside the garment hem, not visible from the outside.
Finish the raw edges of the crinoline to prevent fraying. You can use a zigzag stitch along the bottom edge, or bind it with bias tape. If you use bias tape, sew it to the bottom edge with the walking foot still attached. This gives the crinoline a neat, professional finish and keeps loose threads from catching on your skin when you wear the garment.
Try on the garment and check the shape. The crinoline should hold the fabric out evenly all the way around. If one section is flatter than another, you may have missed a channel stitch or the wire may have shifted. You can add extra stitches by hand with a needle and thread if needed—just follow the existing channel lines.
Common Mistakes to Avoid
The most common mistake is using a regular needle instead of a heavy-duty one. A size 80/12 needle will break the first time it hits the wire core, and you'll waste time replacing it and rethreading. Buy the right needle before you start.
Another frequent error is sewing across the support channels instead of along them. This crushes the wire and ruins the structure. Always look at the crinoline first and identify the direction of the channels. Sew parallel to them, never perpendicular.
Skipping the walking foot is also a recipe for disaster. Without it, the bottom layer of crinoline will bunch while the top layer stays flat, creating wrinkles and puckers that are hard to remove. If your machine doesn't have a walking foot, buy one before you sew.
Finally, don't forget to backstitch at the start and end of every seam. Crinoline is stiff enough to pull regular stitches loose, especially at stress points like the side seams of a skirt. Three or four backstitches take five seconds and prevent your seams from coming apart.
Frequently Asked Questions
Can I sew crinoline by hand instead of on a machine?
Yes, but it's slow and hard on your hands. Hand-sewing crinoline requires a heavy-duty needle and a thimble to push through the stiff material. Use a backstitch and make stitches about 1/4 inch apart. It works for small repairs or hems, but for attaching a full strip of crinoline to a garment, a machine is much faster and creates stronger seams.
What's the difference between crinoline and tulle?
Tulle is a soft, sheer netting with no wire or structure. Crinoline is stiff and opaque, with wire or plastic channels running through it. Tulle is used for layering and creating volume without much shape; crinoline is used when you need the fabric to stand out and hold a specific shape. They're sewn differently and serve different purposes.
Do I have to sew crinoline to the inside of the garment?
Yes. Crinoline is always sewn to the wrong side (inside) of the fashion fabric so it's hidden from view. The stiff side faces outward, pushing the garment fabric out. If you sew it to the outside, it will be visible and uncomfortable to wear.
What if my needle keeps breaking?
You're likely using a needle that's too small or thin for the material. Switch to a size 100/16 needle and make sure it's inserted correctly—the flat side of the needle should face the right direction for your machine (check your manual). Also check that the presser foot is lowered before you sew; if it's raised, the tension is wrong and the needle will break.
Can I wash a garment with crinoline sewn into it?
Check the care label on your crinoline first. Most synthetic crinoline can be hand-washed in cool water with mild soap, then laid flat to dry. Some crinoline is dry-clean only. Never put a crinoline-lined garment in the dryer—heat can melt the plastic or wire core. Always air-dry.
