## Description

Review: Excellent - does the job - Excellent, worked a treat on a hole in my trousers. Simple instructions and has lasted through several washes so far - very impressed and highly recommended
Review: The quality is good but be careful - These patches can literally save your clothes for a fair price. Theoretically, they are easy to use and do not require any needle and cotton wire. If you have scissors and an iron at home, you are done. Nevertheless, the weak points are the corners as they can make the patch lift up. Once this happens, it gets worse and worse and there is nothing you can do to stop it. I suggest to give extra ironing to the corners when applying and make sure the job is done on the flattest surface possible without any cloth wrinkles underneath. Finally, if the trousers are damaged somewhere in between the legs, just take maniacal care to the application as the friction in that area will make everything worse.

## 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. 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: What are the patches made from**

A: If you use the right pens/paint for materials I don't see why not.
