Abstract Thursday 112 - Circles

Thank you Ingeborg for the subject for today's blip.  Had so many ideas, but went with these embroidery hoops in the end.   They are graduated sizes and I have put a piece of embroidery in the centre.  Played with the colour in LunaPic to give it a bit more interest,  and here it is.
I am also tagging it for composition prompt Circular.
