Sparkle meets sarcasm as our magical girl mascot teams up with her undead co-host for helpful chaos and nerdy insight.
Iron-on patches are one of the easiest (and nerdiest) ways to upgrade your outfits. Got a denim jacket that’s dying for a magical girl badge? A backpack that needs a gamer glow-up? A suspicious hole in your jeans that’s definitely not from crawling through a con queue? Iron-on patches are your new best friend.
But before you go full chaos mode with the iron, there’s a bit of prep to do…
🧵 Is Your Fabric Patch-Ready?
Not every fabric plays nice with heat magic. Here’s your cheat sheet:
✅ Best fabrics for iron-ons:
Denim 👖
Canvas 🧢
Cotton & cotton blends 👕
Polyester 🎽
⚠️ Fabrics to avoid ironing (sew instead):
Nylon
Rayon
Silk
Leather
Waterproof, shiny, or sensitive fabrics
Look for this on the label: The iron symbol tells you how much heat your fabric can handle:
❌ = Do not iron
● = Low heat
●● = Medium heat
●●● = High heat
If there’s a big ❌ through the iron, step away from the heat!

🔥 How to Iron on a Patch
Lay your garment flat. If it’s a bag or hat, stuff it with a towel so it holds its shape.
Set your iron to the highest temperature safe for the fabric — no steam!
Place the patch where you want it. Use a fabric pen if you’re picky.
Cover with a cloth (like a pillowcase or tea towel).
Press the iron down firmly for 30–60 seconds. Cover every corner.
Flip it over and iron the back of the patch too — another 30 seconds.
Check the edges. If they lift, re-iron until fully secure.
🧼 Keeping Your Patch Looking Fresh
On average, an iron-on patch will survive about 25 washes, but with these tips, you can keep it going longer:
Sew around the edges for a more permanent hold
Hand wash or use a gentle cycle
Wash in cold or lukewarm water
Turn the item inside out before washing
Avoid tumble drying — air dry if you can
Dry clean if you’re feeling extra fancy
Patches work best on jackets, bags, or anything you don’t wash often. Bonus: it gives them that battle-worn aesthetic Lee loves.
💡 No Iron? No Problem. Try Hair Straighteners!
Yep — in a pinch, hair straighteners can do the trick. Here’s how:
Heat them up
Position your patch
Clamp the straighteners over the patch (carefully!)
Hold for 30–60 seconds
Move them across the patch bit by bit, holding each section as you go
Optional: wrap foil around the plates to avoid getting glue on them
Not elegant, but it works.
