I agree it would be much easier if I could take them back to the shop/my house to take my time to make it right. But it’s not exactly right down the street if you know what I mean.Ouch.
Hopefully you can stretch it back out. I would probably stay away from using steam. Use a spray bottle and wet them with cool water and try to stretch it evenly. It may take several attempts. It would be a lot better if you took them home to do the work.
Thanks ScottGood advise above. They need to be rewet and then pulled back to the original size and position.
Our company would use a C Clamp to hang a weight on each corner and every foot or so along the bottom during drying. The weight would pull them back into position. Jim's ideas of safety pins also works if you can get the right place to pin them to.
amen! a vapor cleaner can also help before pinning. that way you introduce t just the amount of moisture that the fabric will need and will dry faster.You are dealing with dissimilar contents inside the skirt material. If you check you likely have an internal material sewn into the skirt that was over wet compared to the outside fabric. A dehumidifier aimed into a fan will remedy this quickly on site. Operator error is the cause. A couple well placed safety pins during drying will fix it. If you are correcting this days afterwards you will likely need to rewet it just enough.
