OK, so here's a handy home garden hint: If you've tried to lay out a flowerbed
with a curving, serpentine border using string you know what a frustrating
experience that can be. We suggest you try a garden hose. A garden hose makes a
definitive, substantial line that, unlike string, won’t be easily cut or moved
accidentally with a shovel. It is also easy to reshape the hose as you work so
you can get the border just the way you want it to be.
