A sketchbook has been in evidence the past couple of days which now has now been joined by what appears to be the strange graph paper that Mum and Aunty Biscuit have which is rectangles instead of squares.  This paper is used for knitting patterns as a stitch height is four fifths of its width hence the ordinary squared paper would produce a misshapen pattern.  Harrier says you can also get logarithmic graph paper which is even stranger and would produce a totally weird pattern, I can see the logic in that.  Should anyone be unwise enough to leave the sketchbook and paper on the edge of a sofa one of us will attempt to “accidentally” knock it off and investigate further as we have our suspicions that a new project is in the offing.
