I went to Georgia Southern and this is how we did it:
We gave panda pals for like 3 weeks each NM would have a different one every week who took them to lunch, hung out with them.... Whoever there panda pal was the week of pinning would do the pinning ceremony.
After the 3 weeks we would have each of the NMs write down on a piece of paper there top 3 choices for bigs. Then the sisters who wanted littles would write down who they wanted. We had a committee(big/lil, VPNM, VPE, and a couple of others I can't remember) who decided who got who from the lists - we obviously tried to match them with there top choices but lots of things were factors...If the big was a senior and the lil was a freshman we didn't like to do it b/c the big would leave...If the big already had several lils we would see if there was someone who didn't, that kind of thing.
After we made the decisions we would notify the bigs. This woulds begin big/lil week. Everyday the bigs would send anonymous clues, presents...to there lils. At the end of the week we would have something like a scavenger hunt for revealing the lils would get like 5 clues have to go to different places...and in the last place (same place for everyone) the bigs would be hiding. Oh yeah the lils would wear a costume that matched their bigs and that's how they would know they had the right one
The semester I pledged revealing was also the kickoff for our NM retreat.
