I use sheets for backing on some of my quilts..I have had no problem with them using them this way..I have try sheet pieces on scrape quilts..in my opinion it works fine..But I do notice a difference in the feel ..I have had no trouble at all with needles or the sewing of them..u may have just had a loose weave fabric that u were sewing at the time u try the sheet too..Batiks is one of the hardest material to sew on.. the darker the batik..the harder..sheets are simple compare to Batiks...
