Review: That's exactly what it's supposed to do. - This actually worked really well. It was easy to use and took very brief exposure with an iron to make it stick. A nice inexpensive fix for my work shirt with plenty to spare. Thanks.
Review: Great patches - I wanted to wait a bit before writing my review so I could see how these held up through months of wear and washing. I’m happy to report that they were 1. Easy to apply and 2. Have held up wonderfully to wear and washing. No falling off or peeling back at corners. Very happy to have saved a couple pairs of leggings which had small holes develop where the pockets attach.

## Features

- 𝗣𝗮𝗰𝗸𝗮𝗴𝗲 𝗜𝗻𝗰𝗹𝘂𝗱𝗲𝘀: 12 iron-on fabric patches, size 3" by 4-1/4" (7.5 cm x 10.5 cm). Ideal size will help to conceal the shortcomings of both small and large holes and enough to create your own design. Black color will perfectly match your different clothes. Front side of the patches is 100% cotton, rear side is covered with the strongest hot-melt adhesive film. Patches made in EU using high quality materials.
- 𝗘𝗮𝘀𝘆 𝘁𝗼 𝗔𝗽𝗽𝗹𝘆: It will take only a few minutes to repair or decorate your outfit, as only an iron is required. Preheat your iron to the maximum, then place the patch on the desired spot and iron over the patch with pressure for 60 seconds. You don’t have to sew patch on or use further fabric glue, hot-melt adhesive film on each patch is very durable by itself. CAUTION: Do not apply patches using hair straighteners or other heating objects, only use an iron.
- 𝗢𝘂𝘁𝘀𝗶𝗱𝗲 & 𝗜𝗻𝘀𝗶𝗱𝗲 𝗦𝘂𝗶𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆: You can place the patches on the outside of a garment. Use scissors or die-cut machine to cut the patches to the size or shape you want and decorate your favorite clothes. You can also apply patches from the inside of a garment, this way the shiny rear side of the patch shows through the hole. After a couple of washes, the shiny glue will disappear and it will look like normal fabric.
- 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗪𝗮𝘀𝗵𝗮𝗯𝗹𝗲: Applied patches are washable at high temperature; they can also be tumble dried on a high temperature setting. Even if applied patch starts to peel off after some time, simply re-iron the patch again. One patch can be re-ironed at least 3 times, even after washing. To prevent the felting off and curling up, pay special attention to the corners, butt areas and seams when applying the patches.
- 𝗠𝗼𝗻𝗲𝘆 𝗦𝗮𝘃𝗲𝗿: Repair crotch areas, knees, elbows, pockets etc. when it already has tears marks, or use the patches to prevent future problems. Place a patch inside of the garment on a weak spot before the problem transpires, prolong the life of your new clothes. Not only pants and jackets can be fixed, but also sheets, car seats, even socks and many more. Carefully read the instructions of the fabric which you are going to repair, it has to withstand the highest temperature of an iron.

## Questions & Answers

**Q: will this work on a fabric car seat to cover a hole?**
A: They adhere very well when using a heat press. As long as you have a good iron it should work.

**Q: What material is the patch?**
A: Blue jean material

**Q: Can this work on baseball hat material**
A: These patches should work on any material that has a thickness to it.  Fabrics like silk or Jersey are too thin for these patches.  Hope this helps.

**Q: Can you use these patches on jeggings with 51% polyester?**
A: These patches require a high heat in order to adhere to your fabric.  You need to look at your begging label and see what it says about ironing

### ⭐⭐⭐⭐⭐ Great patches
*by K***R on March 27, 2024*

### ⭐⭐⭐⭐ Use it for any repair, but quite thick
*by N***N on May 21, 2021*

I tripped at work and ripped a hole in pants where my knee is, so instead of stitching (which I don't know very well how to do) I used these patches and for the most part I'm very satisfied. I used an entire patch on the inside because it's black and my pants are gray and it would look incredibly tacky, but it's help up very well and the patch isn't coming off at all after a few days of application. However, the patch is quite thick and my pants are pretty thin so there's a hard part of my pants on the knee and it's kind of annoying and looks weird (see pictures). I probably could have cut the patch to not be so big and I have yet to wash these pants and I don't know if washing them will soften the patch and make it look more natural, but I will update this review if it softens after a wash. If you're using this patch on thin clothing like a t-shirt or thin pants, I would try to get something less sturdy unless you're okay with it.. But overall, very satisfied.
