Swirls in silks and fabrics

Mum and I visited the Quilt Show today and as always were bowled over by the variety of work and the standard of all of the quilts. I thought this fitted the weekly challenge of Pattern beautifully - Mum tells me this will have been painstakingly pieced together by hand to create this wonderful swirling , 3D effect. Unfortunately I omitted to take a note of the creators name to give her or him due credit so if you recognise it please tell me.
Becoming a member of the local Quilters Group is on my bucket list for retiral - in fact my name is already on the waiting list. 
The extra is a stunning piece of quilting and embroidery by a lady from devon called Helen Coverly.
