In all my years of knitting I have never encountered a stitch as hard to do as P5tog (purl 5 together). I'm knitting Swallowtail lace shawl by Evelyn Clark which includes a loosely made 'nupp' stitch (k1,yo,k1,yo,k1 into one stitch). I did what I thought was a loose nupp but when I came to the wrong side row the nupp is those 5 stitches purled together. Of course my loosely was nowhere near loose enough so it felt like trying to pen 5 sheep without the aid of a sheepdog. I have now amended the pattern to read VERY loosely.
