Already opened walnut shells (Glasco)

I know I sound nuts but I love these shells that the squirrels have already eaten the center. The shapes are so unique I see a face smiling or an owl. So if you work outside or taking a walk and see them I would love to come and pick them up. I’m making something beautiful with them. If yiu have lots I will even come and pick them up so you won’t have to bend. Thank you so much friends.
