Tried to email you personally but the only address i could find seemed to have a mixture of hyphens and dashes – you must refresh my memory!

My mother was a furious knitter. Any spare time she had she spent knitting. When TV came in she found she could knit and watch so that we, and our extended families, were inundated with sweaters and scarves etc, until the local wool-shop agreed to pay for her efforts.

As children we used to spend hours helping to change the skeins of wool into balls before she could start knitting.
That is one definition of Wool-gathering.

Another definition of Wool-gathering is “absent-minded dreaming” (Chambers); “idle or absent-minded indulgence in fantasy daydreaming” (Collins). I felt this second meaning, needed to start with “one” (i.e. one of the day-dreams).
