(Wig used for Green Arrow from Young Justice)

The main problem I encountered with this wig was making the part of the wig work with the style I was aiming for.

Also, beard and mustache.

(Wig used for Dave Strider from MS Paint Adventures / Homestuck)

I prefer lighter-haired Striders, but I chose this wig back when I first started cosplaying Dave because it was close to my natural hair color. Convenient for when I miss a pin and some of my own hair pokes through!
