These warm and wintry leg warmers have little holes in the upper brim, through which a string is pulled in order to keep them up. At the opposite side is a stretchable brim, you will pick up after the main knitting.

The warmers are knitted from side to side, not from bottom to top. You seam the ‘live stitches’ of both sides with a Kitchener stitch, so there will be no visible seam. Do you find this difficult , an alternative method is described.
