I always wait for them to go on sale and buy them. Mainly because I don't remember using these sheets for more than a year. But I can get two for each horse and then switch between them until I have one. Even when they are at their most uncomfortable, they can easily be thrown in the trash and taken to the cleaning. If they manage to rip it apart before I'm ready to buy more, I use Hobby Lobby Tent Patches. The patches just stick. I pay more for their medium and heavy weights. And the durability of other brands at this weight makes it worth it. But I never want to spend a lot on sheets because no matter how strong they are, I think my boys will still manage to rip them apart. I have all the scales from this brand and am very happy with them. They are true to size and fit well.
