Input: I had high hopes for these sheets even though I got them at a bargain price. They don't have elastic all around, which is a problem with flannels resulting in sheets riding up on the sides. They are also inexpensively made with MANY loose threads and potential for unraveling. They are thin as flannels go. All in all, try to find a better quality sheet.... it's well worth it!!
Output:
Negative
