I just recently installed a full set of double-ended dreads to a blue wig I had purchased. I wanted to do this to show people what it would look like for a full set of dreads, being that I have an undercut, so the "full effect" is lessened by my lack of hair.

 After I installed the dreads to the wig, however, I realized that if someone *really* wanted to, they could do this themselves, instead of attach the dreadlocks to their own "real" hair. This way, a fabulous head of dreads is available in a matter of seconds and can be taken off at any time. :)
