Sew-on backing is the most secure and works on almost any fabric, iron-on is the quickest to apply on cotton and polyester blends, and Velcro (hook and loop) lets you remove and swap patches on uniforms and gear. At Legion Patches, sew-on is included on every order, iron-on adds $0.15 per patch and Velcro adds $0.56 per patch.
This guide compares the three, shows which fabrics each one suits, and explains how to apply them so your patches stay on.
The three backings at a glance
| Backing | Price | How it attaches | Best for | Removable? |
|---|---|---|---|---|
| Sew-on | Included | Stitched by hand or machine | Vests, jackets, uniforms, anything washed often | Only by unpicking |
| Iron-on | +$0.15 per patch | Heat-activated adhesive | Cotton and poly blends, quick projects, team and school wear | No |
| Velcro (hook and loop) | +$0.56 per patch | Hook side on the patch sticks to a loop panel | Tactical gear, plate carriers, bags, uniforms with loop panels | Yes, any time |
All three backings are available on every patch type: embroidered, woven, UV + PVC and PVC.
Sew-on: the most secure choice
A sew-on patch has a plain back and is stitched straight to the garment. It is the traditional method and the strongest. Stitching holds through years of washing, wear, weather and riding, which is why it is the standard for motorcycle vests, work uniforms and department patches.
- Works on: almost everything, including leather, denim, canvas, nylon and fabrics that cannot take heat.
- Downside: it takes time, or a trip to a tailor or leather shop for heavy materials.
- Tip: sew just inside the border with a thread color that matches the edge, so the stitches disappear.
If you are unsure which backing to pick, choose sew-on. It costs nothing extra and never lets go.
Iron-on: the fastest to apply
An iron-on patch has a layer of heat-activated adhesive on the back. Press it with a household iron or a heat press and the glue bonds to the fabric. It is the easiest option for teams, schools and anyone applying patches at home.
- Works on: cotton, denim, canvas and polyester blends that can take a hot iron.
- Avoid on: leather, nylon, rayon, waterproof or coated fabrics, and anything that melts or shines under heat.
- Downside: adhesive can loosen over time, especially with hot washes and tumble drying.
How to iron on a patch
- Heat the iron to the cotton setting, with no steam.
- Place the patch where you want it, adhesive side down.
- Cover it with a thin cloth, such as a pillowcase, to protect the patch.
- Press firmly, without sliding the iron, for about 30 seconds.
- Turn the garment inside out and press the back of the area for another 20 to 30 seconds.
- Let it cool fully before you move or wear it. Check the edges and press again if any lift.
For patches on clothes that are washed often, add a few stitches around the edge after ironing. You get the quick placement of iron-on with the hold of sew-on. Note that PVC patches are generally not suited to ironing, as heat can deform the PVC; choose sew-on or Velcro for PVC.
Velcro (hook and loop): swappable patches
A Velcro patch has the hook side of a hook-and-loop fastener on its back. It presses onto any loop panel and pulls off again, so you can swap patches whenever you like. This is the usual choice for morale patches, tactical gear, plate carriers, range bags and uniforms that already have loop panels.
- Works on: loop panels on gear, bags, hats and jackets.
- Downside: the garment needs a loop panel. Plain fabric needs a loop piece sewn on first.
- Tip: if your garments do not have loop panels yet, tell us when you order and ask about loop pieces.
Velcro pairs naturally with PVC patches, which are waterproof and tough enough for outdoor gear. See our morale patches page for more.

Caring for patched garments
The right backing is only half the job. How you wash and store a patched garment decides how long the patch looks new.
- Wash inside out on a cool or warm cycle. This protects the patch surface and the edges.
- Skip the hot dryer for iron-on patches. High heat softens the adhesive. Air dry or use a low setting.
- Do not iron directly on a patch. Iron around it, or press from the back with a cloth.
- Clean PVC patches with a damp cloth. They are waterproof and wipe clean, so they rarely need a wash.
- Check Velcro panels now and then. Lint in the loop side weakens the grip; brush it out to restore it.
Every Legion Patches order ships with the backing you chose already applied, so your patches are ready to attach the day they arrive. If you are not sure which backing will survive the way your patches will be used, ask us before you order and we will recommend one.
Common mistakes
- Iron-on on leather. The adhesive will not bond properly. Sew it on.
- Ironing nylon or waterproof jackets. The heat can melt or mark the fabric. Use sew-on or Velcro.
- Ironing straight onto the face of a PVC patch. Direct heat can soften PVC. Press PVC iron-on patches from the inside of the garment, or through a thin cloth.
- Sliding the iron. Moving the iron shifts the patch. Press straight down and hold.
- Washing too soon. Give iron-on patches a day before the first wash, and wash inside out on cool.
- Ordering Velcro for clothes with no loop panel. The patch has nothing to stick to. Plan for loop panels first.
Frequently asked questions
Which patch backing is best?
Sew-on is the most secure and works on nearly any fabric, so it is the best default. Choose iron-on for quick application on cotton and poly blends, and Velcro when you want to swap patches on gear.
How much does iron-on or Velcro backing cost?
Sew-on is included. Iron-on adds $0.15 per patch and Velcro adds $0.56 per patch.
Do iron-on patches stay on in the wash?
They hold well on suitable fabrics if applied properly, but adhesive can loosen over many hot washes. Wash inside out on cool, or add a few stitches around the edge for permanent hold.
Can I iron on a patch to leather or nylon?
No. Iron-on adhesive does not bond well to leather, and heat can damage nylon and waterproof fabrics. Use sew-on or Velcro.
What is a Velcro patch?
A patch with the hook side of a hook-and-loop fastener on the back. It sticks to loop panels on gear and uniforms and can be removed and swapped at any time.
