Some things I know after nalbinding weekend:
1) Having interesting yarn is not important. It is better to have no bumps, clumps, extra froofiness and have smooth yarn that is not too grippy and not to slippy. Not plied.
2) If you are doing a lot of spit joining, you do not need to drink Metamucal that day.
3) Nalbinders should stand up and move around a little bit.
4) You should never leave nalbinding unattended as it moves when no-one is looking at it.
