Jenkins was born in Alexandria, Virginia, but first began experimenting with tape as a casting medium for creating sculpture in 2003 while living in Rio de Janeiro. Wrapping the tape in reverse and then resealing it, he was able to make casts of objects including himself. One of his first street projects was a series of clear tape self casts that he installed on the streets of Rio de Janeiro. Jenkins became immediately interested in the reactions of the people and considered his installation as much a social experiment as an art project
