The Shutter Sisters assignment was to photograph something that's always there.
And stop signs are always there - even when you don't think of them or don't realize how they are absolutely necessary.
And then there are the sinks full of dishes - do they never end??? I'm notorious for not drying the dishes. I much prefer air drying :))
I apologize for not linking to Shutter Sisters but their website is down for maintenance so I'll try to link tomorrow.
