I have been sewing on this project for the last few weeks.
The fabric was made over the past two summers, when I used a rolling pin to squish grass stems, leaves and various flower petals between two layers of fabric (mordant with alum). I used the fainter lines to stitch 'grass' and the larger blobs to add some floral stitches. There is a lilac coloured curving line from the bottom left (yours) to the top right. I have begun to add lace and expand the area of stitching. I think it very pretty and it is certainly relaxing to work on. Let's try another photo.
