Review on ZEFFFKA Premium Quality Fabric Patches by Denise Davis

The problem isn't so much in the product itself (although it's plastic, not fabric, no matter what you say), but in the idea. First, use it exactly for the minimum recommended time. If you use the maximum recommended time the fabric will burn/weaken (yes, pure cotton). So I destroyed one of the two shirts. However, excessive heat applied to a small area is never good. It is absolutely not suitable for sewing. Yes, mom, you knew how to do it without anyone seeing. Right now I'm giving it three stars, looking at the second shirt and deciding if I'll drop it even further.
