RE: Need someone to help me fix this... (pic)
I didn't see a picture but I might be able to help. I'm going to assume the headband is knitted also? Is it lined on the inside with fabric or just knitted? If the headband is all knit you should be able to wet it down, stretch it to the new size and allow it to dry. You can also stretch it to the new size and steam (not iron) it until damp and then let it dry. Since you probably don't want to wear it the entire time it's drying, you may want to pin it to an ironing board. If the headband is lined, and it probably is, it will be a little trickier. I'd go to a yarn shop (not inside a craft store but a real one) and ask if they know who'd be willing to do it. Pretty much your looking at removing or at least cutting the lining, reblocking the headband (instructions above) and reattaching or prettying up the lining. Good Luck.
