let me sue you! Most of the repairs of down jackets are said to be made by professional shops, but they just stick a pattern on the broken place, so don't say it's not good-looking, or it will fall off if it's not pasted well! Many of them stick on the iron before it is heated to a certain temperature. As a result, the glue on the decal doesn't completely melt, so it just drops when rubbed! In addition, the price of the decal is about 3 cents, which can be three to five yuan after being affixed to you, which is more than ten times the profit! I'll tell you a convenient, cost-saving and beautiful way. Use cotton thread of the same color as the down jacket (preferably silk thread, thinner). Then sew the broken place on the left and right with eight stitches, and the stitches should be small (if you are a lady, I think you can do it). Then iron it at low temperature. Apply a small amount of white nail polish evenly to the stitches! It's OK when it's dry. The small strip is hard to see. It's much better than decals. Try it! QQ779655965
