Sewing polyester curtains...?
I got these curtains and I went to hang them and realized that for some reason I had 2 scarves and 1 curtain and I can not return them. SO I decided I was going to hem one of the scarves, its the same width, just needs shortened and of course the seam for the rod to go in. I just ATTEMPTED to sew the top part where the curtain rod goes in and its bunched up and is no where near straight. I pinned it in about every 2 inches, but it still did this, does any one have any tips to make it not bunch up when I sew it?
