I use sheets for everything LOL ! Sometimes the front, sometimes the back, just depends on the quilt ! I always get the 100% cotton sheets that " feel nice ". I have a hypersensitivity thing, and things that feel fine to others can sometimes feel REALLY scratchy to me, so I know if I think it feels okay, it is a safe bet that its fine for everyone else too LOL. My personal favorite is a nice Egyptian cotton ! Or those really nice vintage linen sheets . I could pet those forever haha
