1) Buy some 1/2" and/or 3/4" tubing designed for drip irrigation.
Heavy-duty black polyethylene 1/2" mainline costs $14 per 100 feet.
(3/4" mainline costs $20 per 100 feet if you find a bargain.)
2) Run it from your existing spigot around your house or past each bed, burying it or adding a screw-disconnect where you have to mow.
3) Then insert Tees with male hose threads anywhere you want a hose spigot.
(Dripworks part numbers ELMT or ELMT34, $1.60 or $2.24 for the more convenient "Easy Loc" fittings.)
To each of those Tees, optionally screw on a cheap plastic two-valve Y.
(E.g. Dripworks part numbers HYV - $2.50. The brass Y with valves is $10.)
4) Screw one short section of garden hose onto each spigot. For this, cut up a long, cheap garden hose and add male and female hose ends (brass) with hose clamps from Home Depot. Or use the cheaper plastic hose ends / hose menders.
5) Sometimes you won't need the extra shutoff valve, but you can add short branches of 1/2" mainline with sprinklers, sprayers, misters, drippers, drip-line or T-Tape. Being able to shut off a zone of high-volume sprinklers (but leave the drip-lines dripping on a timer) is really handy. You can slowly drip-irrigate pots or large beds for hours that way, and still spot-water by hand anywhere in the yard.
Single-valve fittings for garden hoses were not much cheaper than 2-valve Ys, so I "splurged" and put two valves everywhere.
Black PE mainline is too stiff to use as a garden hose. That's why you need short lengths of regular garden hose at the ends, so hand sprayers and wands are easy to handle.
Dripworks sells ½" PE mainline for $14 / 100 feet. That will deliver 6 GPM = 240 GPH.
Steubers Distributing (local to me) sells ¾" PE mainline for $20 / 100 feet. That will deliver 8 GPM = 480 GPH.
Their wall thickness is 0.050 - 0.055 inch.
