Intriguing! I think I have an idea what it is. I just don´t know the proper word for it in English. It seems to be that kind of sieve where one decants noodles into. Right? ("Nudelsieb" in German...:-))
Even if that is not correct, it seems you could enjoy some early spring sun in your garden today :-)
Yes it is! A colander. After my first post today I went searching for something with holes in it- this gave me the perfect shadows.
A colander, great, I learned something today!
"Nudelsieb" me too!
