My son bought a brand new Carhart jacket and had the back embroidered with the name of the company he went to work for. Well, he's no longer working there and wants me to try to remove the embroidery. It's a large emblem and writing. Does anyone have an idea how i can remove this. A seam ripper will take 10 years or more. Is there a product that will dissolve the thread without hurting the jacket? Any help will be appreciated.
