I just hemmed my husbands pants and now there are the old hemlines that just look horrible. No one else will notice them or even care for that matter but I know they are there and it just really bothers me. So here is what you do if you have the same problem. Dip a rag in vinegar and water and but the damp rag under the article of clothing with the hemline problems. Then iron and it should make them disappear. I will be trying this tomorrow
