I receive these full size sheets and washed them, slept on them a couple of nights. They started to pill(tiny balls). So I i thought I'd wash them again (maybe the sizing didn't come out). Put them back on the bed, slept 2 more nights. More balls! So I thought I'll turn them over, maybe they sewed them wrong side out. More balls. But I must say that Overstock was great about it when I asked to return them.
