I feel like an idiot, but I can't get it right. It's my mom's machine and she isn't home right now. The needle broke, so I got a new one out and put it in. Well I guess it was crooked because it wasn't sewing right. So instead of keep going like I normally would, I stopped. And tried to put it in again, but it's crooked again. What am I doing wrong??? Why won't it go in straight??
