Vortex

Done for abstract Thursday, thanks to Ingeborg for hosting. FYI it is derived from the reverse side of my small sewing cutting wheel.
Another cold day, so only the weekly shop and a trip to the butchers where they were selling thick filled brandy butter mince pies reduced to £1 :-)
As it was too cold to go for a walk, I did an hour on my pedals 473 calories burnt, but most probably put on again with one of the mince pies !!!!! :-)
