How to Patch Jeans with Blanket Stitch for a Durable, Decorative Repair
Colonial Needle Company Blog | By Shannon & Jason
Let’s talk about knees. Specifically, the knees of your favorite jeans. You know the pair. They fit like they were made for you, they’ve been broken in for years, and then one day you look down and there it is. A hole. Maybe it started as a thin spot. Maybe there was a sidewalk incident we don’t need to discuss. Either way, the once faithful fabric in the area of the knee has given up, and you’re left wondering if it’s time to say goodbye.
But wait! The is not the time to bid farewell to those beloved jeans. Not even close.
This month we’re patching a torn knee (or any other area of general wear and tear) with one of the hardest working hand stitches out there: the blanket stitch. And we are not hiding this repair…we’re framing it like a work of art in a museum. A pop of vibrant fabric peeking through the hole, a ring of bold perlé cotton around the edge, and suddenly the hole is the best part of the jeans. We’ll take that textile mishap and turn it into a masterpiece!
One Stitch, Two Jobs
Here’s what makes the blanket stitch such a clever little stitch. When you patch a hole, you actually have two problems to solve. First, the patch needs to be attached and second, the edge of the denim around the hole is raw, and raw edges fray. Leave it alone and that hole runs the risk of creeping outward every time you bend your knee. Now, that said, we love a good frayed edge but, for this patch, we’re going to let the perle cotton take center stage.
The blanket stitch handles both at once. The straight part of each stitch goes down through the denim and the patch, anchoring them together. The loop at the top of each stitch wraps over the raw edge of the hole, holding those cut threads in place so they stop unraveling. One stitch, two jobs. We do love an overachiever!
“Can’t I Just Use an Iron-On Patch?”
We hear this one every time we talk about hand stitched mending, and it’s a fair question. For some things, iron-on patches are fine. Play clothes that will be outgrown by spring? Go for it, no judgment here.
But in our studio experience, iron-on patches tend to lift at the corners on spots that flex all day, like knees and elbows, and they stiffen the fabric right where you need it to move. A hand stitched patch bends with you. It can be removed or replaced down the road if you want to change things up. And honestly? It looks a whole lot better.
Visible on Purpose
There’s a long and wonderful tradition of mending that doesn’t try to disappear. Visible mending says, “Yes, this was torn, and yes, someone cared enough to fix it.” We think that’s worth showing off.
This is the perfect place for that fabric scrap you love too much to let go of, and the thread color you’ve been saving for something special. A bright floral behind dark indigo? Gingham? A little piece of a favorite shirt that finally wore out? All yes! The patch sits behind the hole, so whatever you choose shows through like a window, and the blanket stitch becomes the frame around it.

What You’ll Need
- Jeans or any garment with a hole. Ours had a torn knee, but this works on elbows, pockets, tote bags… if it has a worn spot or a rip, grab it and patch it up.
- Fabric for the patch. Solid or patterned, your call. Since it shows through the hole, pick something you’ll enjoy looking at.
- Presencia 8 weight perlé cotton. A twisted, non-divisible thread with a lovely sheen and enough body to wrap a raw denim edge and stand out against it. Contrast is your friend here.
- John James embroidery needle. The sharp point gets through denim, and the long eye makes threading perle cotton a lot less fussy.
- Thimble Crown. Stainless steel with a dimpled surface and a raised edge that keeps the needle from slipping. It sticks right to your finger with an adhesive pad, which means Shannon gets to keep her manicure. (Longtime readers know how we feel about this little thing. If you missed it, catch up [here].)
- Roxanne Glue Stick. Water soluble and acid-free. It holds the patch in place while you stitch, so you can skip the pins.
- Roxanne Quilter’s Choice White Marking Pencil. Pure chalk and water soluble, it shows up crisp on dark denim, which is exactly what you want for a stitching guide.
- Scissors and an iron.
Let’s Stitch!
Step 1: Tidy Up the Hole

Trim away the loose, stringy threads hanging into the opening so you have a clean edge to stitch around. Don’t try to turn it into a perfect circle or square. Keep the shape your jeans gave you. It’s part of the story.
Step 2: Cut Your Patch
Cut your patch fabric about 1″ larger than the hole on all sides. That extra inch gives your stitches plenty to hold on to, and anything you don’t need gets trimmed away at the end.

Step 3: Glue It in Place

Turn the jeans inside out or reach up inside the leg. Before you glue anything, slide a piece of cardboard inside the leg. Trust us, you do not want to glue the front of your jeans to the back.
Run the Roxanne Glue Stick around the hole on the wrong side of the denim, then press the patch in place with its right side facing the hole. That way, the side you love is the side that shows.
Step 4: Heat Set
Give the patch a quick press with a dry iron. The heat sets the glue so the patch stays put while you stitch. Skip the steam here. The glue is water soluble, and moisture can soften it before it has a chance to set.
In our studio, this little step is the difference between stitching through denim feeling fiddly and feeling easy. No pins poking you. No layers sliding around. Just you, your needle, and a patch that stays exactly where you put it.

Step 5: Mark Your Stitching Line

Use the white marking pencil to draw a line all the way around the hole, about 1/4″ back from the edge. This is your guide for stitch depth. Every stitch goes down on that line, so even if your hole is wonky (and let’s be real, it probably is), your stitches stay consistent all the way around. Bonus: the pencil mark is water soluble, so it rinses away when you’re done.
Step 6: Blanket Stitch Around the Hole
Thread your needle with about an arm’s length of perle cotton and knot the end. Then:
- Bring the needle up from the back, right at the edge of the hole.
- Go down on your pencil line, through both the denim and the patch.
- Come back up just inside the opening, through the patch, with the working thread looped under the needle tip.
- Pull through snugly. Watch the thread wrap over the raw edge. That’s your first blanket stitch!
- Move over about 1/4″ and repeat, working your way around the hole.
A few things we’ve learned along the way:
- Snug, not tight. Denim at the knee needs to move. Pull your stitches too hard and the patch will pucker. If you are patching a different area or stitching through a lighter weight fabric, make sure your thread tension matches the fabric so the finished patch doesn’t pucker or pull at the surrounding area.
- Mind the curves. Around tighter curves, take slightly smaller steps between stitches so the loops stay snug against the edge.
- Let the thimble do the pushing. Denim plus a patch is two layers, and denim pushes back. Your fingertip will thank you.
- Running out of thread? Take the old thread to the back and knot it. Start your new length by coming up inside the last loop and carry on like nothing happened.

Step 7: Close the Circle and Tie Off
When you’ve stitched all the way around, slip the needle under the loop of your very first stitch to connect the end to the beginning. Take the thread to the back, weave the tail under a few stitches before tying a knot and trimming the tail.
Step 8: Trim the Excess
Turn the jeans inside out and take a look. If there’s a lot of extra patch fabric beyond your stitching, trim it back, leaving about 1/2″. That keeps the inside of the knee smooth and comfy to wear.
Caring for Your Mend
Both the Roxanne glue and the chalk marks are water soluble, so they’ll come out in the wash. Just wash your jeans the way you normally would. If you like to baby your mends (we see you), turn the jeans inside out first but the Presencia Perle Cotton is strong enough to stand up to a lifetime of washes,
Every Hole Is an Invitation
Mending is one of the most quietly rebellious things you can do with a needle and thread. Every patch says this garment is worth keeping, and so is the time you spend on it. We call this way of thinking Wardrobe Architecture: treating the clothes you already own as something to build on, repair, and keep, instead of something to replace. If you want to dig deeper, our Mending Handbook is packed with techniques like this one.
So go dig out those jeans with the busted knee. Grab a scrap you love and a thread that makes you happy. Your favorite pair isn’t finished. It’s just getting started on its next chapter.
