Given that JungleJim is setting the bar at 2 jigs, I fully plan on doing 2 jigs as well. Having said that, I just finished a 2 jig per participant on another forum and not as many participants but....... Several packaged 1 jig per bag and sent 2 bags, the others either did 2 jigs in one bag or 2 individually bagged jigs bagged in a third larger bag.
It was a bit confusing and I sort the jigs into solo cups then take 1 from each cup for each participants envelope I ended up with 18 cups for 11 participants, ran out of room but got them properly sorted and distributed.
Since this is JungleJims first swap, try to make it as easy on him as possible.
