getting creases out of stitching fabric by: Phyllis
Have you tried using a cold damp cloth on the inside of the crease and instead of moving the iron back and forth, put it down directly on the crease and hold it (steam it) down for a few seconds?
Pick up the iron and move it over to another spot. If this doesn't work, you could take it to a 'professional' (not just anyone) dry cleaners and they will remove it for you. I had a yard of AIDA fabric that I tried the old fashioned way of 'pressing' it and didn't remove it so well. I took it to my dry cleaners and 'bingo', came out beautiful.
Ask them 'not to fold it across a wire hanger' when it is finished.
