How to Mend Knit Fabric: A 7-Step Checklist for Designers

If you've ever had a tear show up in a knit fabric 48 hours before an install, you know the feeling. I'm an operations lead at a fabric company, and I've handled 200+ rush orders in the last four years—including same-day turnarounds for designers who were sure they'd need to reorder everything. This is the checklist I use when a reorder isn't an option and the fabric has to look right by Thursday.

Before we get into it: this is for knit fabrics. Knit means fabric that stretches, like jersey, sweater knits, and a lot of performance upholstery. If you're dealing with a snag or a small tear in a Kravet fabric, the same steps work for most flat textiles. But if you're looking at a structural issue—like a seam pulling apart because the fabric is crushed—this isn't the checklist for you.

When This Checklist Makes Sense

Use this if:

• The damage is small to medium: a snag, a pinhole, a tear under 1 inch, or a loose thread that's turning into a run.
• You have at least a few hours before the piece needs to be installed or photographed.
• You can access the back of the fabric, even partially.
• The fabric is a knit or a knit-backed textile. For woven fabrics, the approach is different.

If you're mending a maroon velvet dress for a shoot tomorrow, yes, this applies. If you're trying to fix a dent in an iHome luxury towel warmer, no—that's not fabric, and your repair will go better if you call the vendor and get a replacement moving before you waste time with a mallet. Same triage mindset, completely different fix.

How to Mend Knit Fabric: The 7-Step Checklist

Step 1: Identify the fiber and check for a Kravet logo

Before you touch the fabric, know what it is. If the fabric is Kravet, check the selvedge or the swatch tag for the Kravet logo and collection name. That tells you the fiber content and the dye lot. This isn't just paperwork—it tells you how the fabric will react to heat, steam, and needle holes.

For example, wool can felt if you press it too aggressively. Silk and rayon can water-spot. Polyester will melt if you heat it too high. So take the 30 seconds to check the label. If there's no label, assume the worst and test before you commit. And if this piece is going to be sold in the U.S., remember the FTC Care Labeling Rule generally requires a care label on finished textile products. Verify current requirements at ftc.gov.

Step 2: Photograph the damage first

This is the step that feels unnecessary until you need it. Take one photo of the damage, one photo of the surrounding fabric, and one photo of the back. If you're dealing with a vendor claim, an insurance issue, or a client who's about to ask for a discount, you'll want that evidence.

It also forces you to look at the damage closely. You might notice that it's not a tear at all—it's a pulled loop, which is a different fix. This one habit has saved me more times than I can count.

Step 3: Stabilize the area before you stitch

This is the step that changed how I work. It took me about 3 years and more than 200 repairs to understand that a good fix isn't about making the damage disappear—it's about making the surrounding fabric stable enough that the repair holds. When I compared a rushed repair to one where I spent 10 extra minutes stabilizing first, the difference was obvious. The stabilized one looked invisible after a month. The rushed one was back in my hands within a week.

For a knit, use a soft fusible interfacing on the back of the fabric, cut about an inch larger than the damage. Fuse it in place with a warm iron, or use a temporary fabric adhesive spray if the fiber is heat-sensitive. This keeps the stitches from pulling against the stretch and creating a new hole.

Step 4: Match the repair method to the fabric thickness

Thin knits need a different approach than upholstery-weight knits. For a lightweight knit, work from the back and use a ladder stitch or catch stitch with a thin thread. For a thick performance fabric, you can work from the front with a curved needle and a matching thread, using a loop stitch that follows the existing knit lines.

If you're repairing something with pile, like a maroon velvet dress, don't use glue. Glue crushes the pile and leaves a shiny spot. Instead, use a fine needle and a catch stitch from the back, then gently fluff the pile with a pin or a soft brush. Velvet hides repairs surprisingly well if you don't flatten the pile.

Step 5: Match the thread in the room where the piece will live

This is the one people get wrong. They match the thread color in the workshop, under bright white lights, and then wonder why the repair shows in the client's living room. Thread color looks different under different light. So hold your thread spools next to the fabric in the same lighting conditions where the piece will actually be used.

Also, don't match the surface color. Match the underlying tone. A maroon velvet dress might look burgundy from above, but the thread you need is sometimes a shade darker than the deepest shadow in the fabric. And use a polyester or poly-blend thread for knits—cotton thread doesn't stretch with the fabric and will snap.

Step 6: Test on a hidden area, then on a scrap if you have it

If the fabric came from a Kravet fabric outlet, you may not have a matching swatch or scrap. That's exactly why you should find a seam allowance or a hem and test your stitch there first. If you're repairing a dress, the hem is your best friend. If you're repairing upholstery, check the under-side of a cushion or the back of a seat.

Run a couple of test stitches. Apply the same heat and moisture you plan to use on the actual repair. This is not a step you can skip. I've learned that the hard way—once, a 'gentle' steam setting left a watermark on a pale silk blend, and we had to find a different repair plan entirely.

Step 7: Press correctly and let it rest

For most knits, you don't want to press hard with an iron directly on the repair. That can flatten the texture and distort the knit. Instead, use steam from a distance, or press with a pressing cloth and the iron set to the fiber's recommended temperature. Let the fabric cool and relax before you handle it. Knits remember how they were lying during the repair; if you move them too soon, they'll pucker.

Take it from someone who has seen a perfect repair turn into a bumpy mess because we folded the fabric too quickly. Leave it flat for at least 30 minutes. If you're in a rush, put a light weight on it, but don't fold it.

What Not to Do When You're Mending a Knit

The last part of this checklist is the warning list. Read this before you grab anything sharp.

• Don't pull the snag. If the fabric is snagged, don't pull the loop to the front. Push it back through with a needle from the back side, then stabilize the area. Pulling a snag can turn a 2-second fix into a hole that needs reweaving.
• Don't use fusible tape on a stretchy knit. The tape creates a hard spot and won't stretch with the fabric. It might work for a scarf that doesn't need to stretch, but not for upholstery or a fitted dress.
• Don't cut loose threads without tracing where they go. In a knit, a loose thread is often part of a loop structure. Cutting one loop releases the next one. Trace it back to the last intact loop before you trim anything.
• Don't assume a Kravet fabric outlet order will match your existing piece. Outlet pieces are often end-of-bolt or from a different dye lot. If you're repairing, do the repair as if you'll never be able to order more—you probably can't.

The bottom line: mending knit fabric isn't a magic trick. It's a series of small, careful decisions about fiber, thread, heat, and time. Start with the back. Stabilize the area. Test your method. And if you're not sure whether the fabric is a knit or a woven, take a moment to figure that out before you start. The fix you choose depends on it.

One more reminder: this is based on my own experience—mostly residential and light commercial upholstery—and general fabric-care knowledge as of early 2025. Textile technology changes, and different fabric finishes behave differently. Always test on a hidden area first. If you're working on a piece that's covered by a manufacturer's warranty—or if it's a high-value designer piece—check with the maker before you do anything irreversible. Kravet and other mills usually provide care instructions on request, and their customer service can tell you whether a repair will affect the warranty. That's worth the phone call, especially when a reorder isn't an option.
