That would be my Reno (AC version) wig. At the time I made it, I had only styled one wig before and it didn't even cross my mind that wig heads are smaller than our heads. So I was way over my head before I even started.
So hours of styling on the tiny wig head later and I finally try it on. It's smaller than my hairline by like 2" in every direction. By some fluke chance, I got my hair dyed nearly the same colour so I was able to wear the wig without it looking too odd.
But lesson learned! Stretch your wig out and pin it that way when you style a wig on a wig head! >_*
