Small Sketches in stitch this past week

These are sketches created over the last weekend.

I've been reading about structures, both cellular and crystalline. These are 2 small stitched pieces that came from my thoughts.

I don't usually use hand-dyed fabrics or commercially dyed fabrics, although I do advocate for using what one has on hand. The colored pieces are from scraps I collected from an acquaintance. 
I will most likely use eco-dyed bits and pieces for a more-fully-realized artwork.
