Sewing/Fabric knowledgable people. Help please

[lurker172602]

I have a skirt made from cotton/elastin fabric (I think, it hasn't got a label but it's a poplin sort of weight and a bit stretchy). The hem has gone all "frilly". It looked as if the sewing thread had shrunk and gathered the fabric. I have tried unpicking it, pressing the fabric and sewing it back up but it still looks the same.

What can I do to fix it, or is it irreparable?

Lurker - has your grandchildren to be count, increased to two now?

Fusible hemming web.  Press about 20cm at a time, using a pressing cloth to prevent any of the fusible sticking to the iron when it melts.

Well spotted am   Yes, two of our sons partners are expecting babies mid year.  We are all very excited. 

Thanks for your your advice everyone.  I have decided to ditch the skirt and buy another one when I see something I like.  It's not worth the hassle anymore to try to fix this one.
