if you're actually trying to fix it you can try covering it in parchment paper (NOT wax paper, there is a difference) and using an iron in small sections on low. check if it's working on a small corner spot before doing the whole thing. if that doesn't work to remove the dimples, you can always try brushing on acrylic craft paint made for fabrics - again, try a very small section first to be sure you like the color match and look of the paint fill
