(This course could be made into a half-day, hands-on workshop.)
It isn't "rocket science" as they say and it's not all that expensive. All you need is a pair of scissors, some tubing and a few small parts and you're all set. You can build enough in one morning to do all your beds. The neat thing about drip irrigation is that it ALWAYS puts the water where it's needed and, if you purchase a battery-powered timer, WHEN it's needed.
