Whole Cloth Pebbles Abstract

I'm trying a whole cloth quilt technique to interpret one of my abstract designs. 

First I used a Frixion Pen to draw the design onto some cotton. The pen rubs out with the heat of friction or with an iron.

Next I quilted the whole design using thick wadding to make the pebbles raised.

The grey stripes were painted with acrylics with a little textile medium added.

For the coloured sections I used watercolour pencils activated with textile medium.

The whole thing is stretched over a frame.
