what will happen if i tumble dry a pair of non tumble dryable curtains?

[chimchar]

they are ikea very long flimsy 35% cotton, 65% polyester curtains.

need to wash them and hem them. cant dry outside at the mo....

whats the worst that will happen?!

They'll shrink.

They'll shrivel and go out of shape. If it were me I'd tumble dry them on cool, but I'd check on them every once in a while. Or just sling them over a door to dry for a few days

I do not know but I always hang my curtains back when still wet, they dry and look fine without drier or ironing.

They will shrink.

instructions said to allow 15% shrinkage. they are wayyyy too long, and too wide too, so shrinkage wont be a problem really unless they shrink to dolls house proportions!!

(disclaimer...they sound awful, but actually look ok!!)

thanks everyone.

I always machine wash on 40% my dry-clean only curtains and I always re-hang them straight from the washing machine. The weight of the moisture in them pulls the creases out especially if fully closed.

Chimchar, if they are a mix of fabricas, they will not shrink evenly and you might end up with wavy curtains, be carefull.

Even if you say shrinkage isn't a problem, there isn't any guarantee that they'll shrink evenly so don't be tempted! The fabric might wrinkle up or distort.

fabrics, not fabricas!

Ahhhh. Shit! Ok. They are washing as we speak. I guess if I give them an extra spin I can hang them straight up.

I have bought some weighted string stuff and iron on hemming tape to do the hems. I suppose I'd better wait until they are dry before doing any cutting of fabric then?!

Really appreciate your help.
