Whenever I knit multiples it’s a good pattern.  Vancouver, Washington’s Rebekah Sturtevant (a/k/a Bekah.knits) has come up with a winner.  Her Moc-a-socs, in both adult and baby sizes, combine a comfy slipper with the top of a sock.  For little ones, this is footwear with staying power.  They won’t kick off easily.  For grown-ups, they are cozy as can be.  Coat the soles with some non-skid product if home has non-carpeted floors because taking a flying header is probably not what the doctor ordered.
