We recently moved into a place with a lot of hardwood floors and so we needed to put down about 5 area rugs. A lot them arrived rolled up and we unrolled them there was lingering curl that we needed to more or less press out.
It's been a couple months now and two carpets still have curl remaining in one corner that doesn't seem to want to settle. At this point, I've tried placing books on the curl for a couple days, folding the curl under itself to try and force it out, and of course just giving it time to work out but it doesn't seem to want to go away.
If it matters, the others which did settle out seem to vary a lot. One has a heavy pile, the other two have a very thin pile.
Is there anything else I should be thinking about or trying to get the curl to work out?
