See post #9856, those are the instructions I followed.Dooneybaby, were you nervous about ironing out the sagging? I just purchased a pre-owned GST with slight sagging, but I'm afraid I would ruin the bag. Can you give step-by-step instructions how you did it. It would be greatly appreciated!
I used an all-cotton pillow case to place over the part of the bag I was ironing. I placed the setting on "SILK" with steam. Then as I moved the iron over the corner of the bag where the sagging was, I used my other hand to press down on the bag, about 1 inch above the sagging, while pressing in the side of the bag. You want to create a flat plane so there won't be a crease or sagging fold.
Essentially, the hand that's on the bag is going to be covered by the white pillow case.
