How to Put Patches on a Letterman Jacket the Right Way
The short answer: sew your patches on. A letterman jacket is built to last for decades, and the patches on it are earned, not decorative afterthoughts. Ironing or gluing them might feel faster, but stitching is the only method that survives wear, washing, and the wool-body-with-leather-sleeves construction most jackets use. If you want your chenille patches to still look sharp at your ten-year reunion, a needle and thread beats a hot iron every time.
That said, there is a right way and a wrong way to do it. Placement matters. Order matters. And a few small habits will save you from lumpy, crooked, or peeling patches. Here is how to get it right.
Where do patches go on a letterman jacket?
Tradition drives most of the layout, so it helps to know the unwritten rules before you thread a needle. The large chenille letter, usually your school initial, sits on the left chest, over the heart. Your sport or activity pins and smaller emblems cluster around or just below that letter. The right chest is typically reserved for your name or a personalization patch.
Sleeves tell your story year by year. Award stripes, service bars, and year patches run along the upper left sleeve, while the right sleeve often carries mascot patches or club emblems. The back of the jacket is prime real estate for a large team or mascot patch, and many people leave it for a single standout piece rather than crowding it. If you are planning a full build, learning how to arrange your letterman patches before you sew anything will save you from unpicking stitches later.
Should you sew or iron patches on a letterman jacket?
Sew them. Iron-on adhesive needs even, direct heat and a flat, heat-safe surface to bond properly, and a letterman jacket gives you neither. Wool bodies scorch, leather and synthetic sleeves can blister, and the quilted lining traps heat unevenly. Even when an iron-on patch sticks at first, the bond breaks down after a few wears and washes, leaving curling edges and sticky residue.
Sewing also handles weight better. Chenille patches are thick and heavy compared to flat embroidered ones, and adhesive alone cannot hold that mass through a season of daily wear. A stitched edge distributes the load and keeps the patch flat. If a patch already has an iron-on backing, you can still tack it in place with the iron for a few seconds to hold it steady, then sew around it for real durability. Think of the heat as a temporary pin, not the actual attachment.
What you need before you start
Gather your supplies first so you are not hunting for scissors mid-project. You will want a heavy-duty hand-sewing needle or a sewing machine with a denim needle, polyester thread that matches the patch border, sharp fabric scissors, straight pins or fabric-safe tape, tailor's chalk, and an iron with a pressing cloth. A thimble is worth having for pushing the needle through thick chenille and wool.
Choose your thread color to match the patch edge, not the jacket. Matched thread disappears into the border and hides small stitch imperfections, which is exactly what you want on a piece people will look at closely.
How to sew a patch on a letterman jacket step by step
Start by laying the jacket flat on a table and positioning every patch before you commit to anything. Use chalk to lightly mark each corner, then pin or tape the patches in place. Put the jacket on and check the layout in a mirror, because patches that look centered on a table often sit too high or too low once the jacket is worn. Adjust until it looks right on your body.
Once you are happy, work one patch at a time. If the patch has an iron-on backing, press it for a few seconds through a cloth to hold it still, then remove the pins from that patch. Thread your needle and knot the end, then bring the needle up from inside the jacket so the knot hides behind the lining. Stitch around the entire border using a whip stitch or a straight running stitch, keeping your stitches small, even, and close to the patch edge. Space them roughly an eighth of an inch apart for a secure hold.
Keep your stitches snug but not so tight that the fabric puckers. When you reach your starting point, knot the thread on the inside and trim the tail. Repeat for each patch, and resist the urge to rush the large chest letter, since it is the most visible piece and the one people notice first.
Can you machine sew patches onto a letterman jacket?
You can, and it is faster for flat patches, but go slow and use the right setup. Fit a denim or heavy-duty needle, drop the feed dogs or use a free-motion foot for tight curves, and test your tension on a fabric scrap first. Machine sewing works best on the jacket body; sleeves are tricky because they are tubular and hard to feed flat under the presser foot.
For thick chenille patches, hand sewing usually wins. The bulk can jam a machine or produce skipped stitches, and you have far more control turning corners by hand. Many people machine-sew the flat sleeve stripes and hand-sew the heavy chest letter, getting the best of both.
How to keep patches looking good for years
Care is where most jackets get let down. Turn the jacket inside out and wash it as rarely as possible, spot cleaning instead when you can. Never toss a patched letterman jacket in a hot dryer, since heat warps chenille and can loosen adhesive backings under stitched patches. Air dry it flat so the weight of wet wool does not pull your stitches.
Check your patch edges once a season and re-tack any threads that start to loosen before they unravel fully. A minute of maintenance beats re-sewing a whole patch. Store the jacket on a wide hanger rather than folded, so the patches stay flat and the wool keeps its shape.
The bottom line
Putting patches on a letterman jacket is not complicated, but it rewards patience. Plan your layout on your body, not just the table, sew instead of iron, and give the big chest letter the care it deserves. Do that, and your jacket becomes exactly what it is meant to be: a record of everything you earned, built to last as long as the memories.

Should I iron or sew patches on a letterman jacket?
Sew them. Ironing does not bond reliably to wool bodies or leather and synthetic sleeves, and the adhesive fails after a few wears and washes. Stitching holds heavy chenille patches flat and secure for years. If a patch has an iron-on backing, tack it briefly with heat to hold it in place, then sew around the border for a lasting hold.
Where does the big letter go on a letterman jacket?
The large chenille letter, usually your school initial, goes on the left chest over the heart. Smaller sport pins and emblems cluster around or below it, while your name or personalization patch sits on the right chest. Award stripes and year patches run along the sleeves.
Can you machine sew patches onto a letterman jacket?
Yes, for flat patches. Use a denim or heavy-duty needle, go slowly, and test tension on a scrap first. Machine sewing works well on the jacket body but struggles on tubular sleeves and thick chenille patches, which are easier and cleaner to sew by hand.
How do I keep patches from falling off my letterman jacket?
Sew patches with small, even stitches close to the border, wash the jacket inside out and infrequently, and never use a hot dryer. Air dry it flat and check the patch edges each season, re-tacking any loose threads before they unravel.
