Collage embroidery

A challenge by fiber artist Merrill Comeau, we were to use fabric scraps to form a collage with added stitching. Here are my two attempts;

The base cloth was a piece of lightweight denim. Most of the fabrics were cut offs and scraps from mask making.

The back fabric with netting to hold everything in place. I utilized the transparency with my embroidery stitches of weeds.
