Well, they don't.
More metal colanders.
Don't hate me, but I seem to find them everywhere I go.
First- my favorite so far. White and red.
The very last one is not as old and is a heavy stainless steel. I'm using that one. I know, it looks filthy. It was. Two words- Magic Eraser.
The rest end up on the wall, in my garden or lined up for some future projects. Some of you have asked how much I pay for these beauties- .25 to $2. I never go over $2. Some would say I'm cheap. Heck, I'd say I'm cheap.
