Alex is a member of Alpha Phi Omega, a co-ed service fraternity on American University's campus that devotes themselves to helping others.  When a friend asked if he knew anyone who could sew their letters, he took the opportunity to learn the sewing machine in the space.  After a lot of practice with much less important fabric, he was confident in his abilities to sew the letters.  It was a long and arduous process, taking about 4 hours for both shirts!  But it was worth going slowly since it was something he only had one chance at.
