The last time we moved, we packed our used pieces of shelf liner. Every bit, from every cabinet. Then we re-cut and re-used it in our new kitchen. That's how durable this stuff is — and how much we love it.
As the company says, "The difference is the ribs!" See details, below...
We love shelf liner and won't stock a new kitchen without it. But most of the stuff on the market is either thin and ugly (retro flower patterns don't do it for us) or else that puffy, pseudo-spongy, waffle-weave stuff.
LifeLiner is simple and unobtrusive. (We prefer the clear, but it also comes in white and beige.) It lies flat without any adhesive, makes a thick, sturdy base for dishes and pots, and it's easy to wipe clean.
And the ridges! The ridges provide a little grip, but they are also so, so great for glassware. We store our wine glasses right-side-up and upside-down, alternating, to save space, and the raised lines allow air to flow around the glass. We frequently put glasses away with water droplets still clinging, and they always dry spotless.
Back when we started using LifeLiner, it was hard to find. But now, you can get it at Bed, Bath, and Beyond or online:
A little bonus about the ridges: They are like measuring marks, making it easy to cut pieces to fit shelves.
