Striped Dr Who type scarf

Be bold and create this lovely cosy multi-coloured scarf,
and use up your stash at the same time.
It uses a provisional cast on and is knitted in the round so
it is a double thickness when laid flat. This also means no
purling! Both ends are then bound off flat using a 3 needle
bind off.
The pattern is designed for DK (light /medium worsted)
weight but any yarn can be used.
Gather many colours of similar weight yarns and pick them
at random while knitting your scarf.
Uses approximately 150g
