At the top of our garden is an enormous field. When we first moved here ( gosh 35 years ago!) it was several fields until they uprooted the dividing hedges. This year it has oil seed rape in. The seed heads are now dry and rattle when you shake one.
Rubbing of a seed head.
The patterns of the stalks and seed heads are rather intriguing. Fly stitch I think.
This little book in a box sold yesterday in the Guild at 51 Gallery. Lovely! Inspiration to make another with a different theme.
