I have a velvet nightgown that rolls up at the hem. How do I correct this problem.?

I have tried undoing the hem but it still rolls up a lot--like 6" of fabric. Its like a rope around the bottom.

You can get weighted cord that they sew into the bottom of net curtains to keep them taut between top and bottom.

Nothing will help. Its the way the material is woven.

Sew in a liner and use backing on the new hem
