One time I was sewing a pair of shorts for one of my kids. I don't recall exactly how I did it because it doesn't bear thinking about too closely, but somehow I sewed side to side instead of front to back and ended up with a pair that had a huge round waist and tight skinny legs. I probably could have ripped the seams out and fixed it, but I was so mortified I tossed the whole thing. And no, it wasn't even my first time sewing shorts!
