Dunzy 60 Pcs Blank Leatherette Hat Patch with Adhesive Rectangle Leather Hat Patches Rustic Faux Iron on for Fabric Repair Custom Sewing Laser Engraving DIY Crafts(Khaki,3 x 2 Inch)

I find them very good.

I initially had some problems with these patches. I've used another brand and there was a plastic backing that needed to be removed before you could use the hat press. I couldn't get the plastic off the backs of these and they weren't sticking to the hat using a hat press at 275° and 20 seconds so I contacted the seller. I was told that the plastic is not supposed to be removed and it's part of the adhesive. After some trial and error, I found that if I set my hat press to 350° and 30 seconds, they work fine.

Good size patches for lasering with your own design. Although they have an iron on adhesive backing I found this not very effective especially if applying to a cap as the heat needs to be applied from the inside as ironing the front can damage the patch and any design on it. The solution is to use fabric glue and ignore the adhesive backing.

I'm torn with the star rating here because the items arrived fine, the quality of the stiching was good and the product was clean. I can't review these for their intended purpose but I wanted to share my experience with Sublimation. In all fairness, the vendor says these are for Laser Engraving and doesn't mention . There is a photo with color in the advert so I was hopeful (my fault, not the vendors) so my rating is primarily based on the appearance of the material and maybe helpful info in the advertising. These patches do not have a paper backing which should have been my first clue that they were not for sublimation. This caused me to do some research on adhesives and I realized that the typical 380F+ sublimation temperature is likely to degrade the adhesive backing. Forging on then, I did a couple of tests at ~360 to 370 degrees in my press for about 70 seconds each. The sublimation paper stuck to the patches (again a sign that these are not designed for sublimation) but they did clean up when the paper was dissolved in running water. There are a few things with these that make them unacceptable for my work. 1) Under the higher temperature, the texture induced to make these a Leatherette is basically gone. In place is a rather blotchy background. 2) The overall contrast between my printing and the patch is less due to darkening of the patch. My guess is this isn't so much of a problem if heat and pressure is just being used to fix it (like with an iron as indicated in the listing). 3) One plus has to do with the threading. As I was worried about the adhesive degrading, my plan was to use another heat and bond type adhesive after sanding off the damaged adhesive. The sanding with 400 grit was very quick and since the stiching held even as I removed the backside (presubably because the existing adhesive filled the holes.)

Les badges sont très beaux mais l'adhésif est insuffisant. J'ai ajouté un adhésif supplémentaire afin qu'ils collent mieux à mes projets !
