It always wants to ride up the sides of my bed because elastic never wants to hold it in place. When I wash and dry my sheets it inevitably spirals up in the washer and dryer so it never washes or dries properly. Then it’s a pain in the ass to try and fold neatly.
I feel like I’m failing adulthood after being bested by a bedsheet.
I dry my sheets separately because otherwise yeah, a bunch of clothes get stuck in the fitted sheet and don’t dry. Honestly I never have the issue of the elastic failing to keep it on the bed, and I toss and turn a lot. You might just need new sheets if the elastic is starting to fail, or better sheets. Or maybe they’re not quite the right size for your bed.
