I'm finally retiring this annoying thing:
I got sick of buying the replacement sponge heads. Instead, I'm going to use these dishrags:
They're great dish scrubbers, they're washable and reusable, and best of all, I can make them myself (knitting pattern here)! I have several left over from a knitting phase a few years ago, and more recently, with my knitting on hiatus,* I bought some at a winter farmers' market. The woman at the booth was surprised. "The older ladies are usually the only ones who know what they're for," she said.
Hurray for older ladies' wisdom!
*the reason my knitting (and anything else requiring both hands) is on hiatus? Hint: this is me right now, typing with one hand on the laptop.
