Wow that's impressive! May I ask, how did you clip the ponytail to the wig? You used, like, bobby pins or similar stuff, or there's somewhere where you can buy clips like the ones ponytails for sell have?
I basically took that extra hair, tied it together and hot glued it onto the clip. (Though a lot of it sheds since it's not really as secure as I should have made it. XD) Then I just clip it to the place I want on the wig! Next time I decide to make my own pony-tail clip, I'll try to secure it all together better so hair doesn't come out.
