Lace knitting is a style of knitting characterize by stable "holes" in the fabric arranged with consideration of aesthetic value. Lace is sometimes considered the pinnacle of knitting, because of its complexity and because woven fabrics cannot easily be made to have holes. True knitted lace has pattern stitches on both the right and wrong sides; knitting with pattern stitches on only one side of the fabric, so that holes are separated by at least two threads, is technically not lace, but often called "lacy knitting".
