A friend in Tianjin said that they have a pattern sticker attached to clothes, just like a trademark. With an electric iron, icons can be attached to clothes without falling off. There are all kinds of patterns. I don't know what their names are. A pack is several yuan, and a pack is nine.

This thing has been available in Tianjin since the 198s. Do you remember that you used to buy the cloth flower, a little animal pattern and so on on children's clothes? It was a few years later than that, but it is rare now!
