Not laundry, but still possibly racist ...
My husband wears an eye patch. He has several which are hand painted on black fabric. The standard eye patch elastic is too short and too thin so it gives him a headache. I replace the thin elastic with a wider elastic long enough to fit around DH's big head. Naturally, I want to use black elastic.
I went to WalMart because they have the best prices in town on sewing notions. They had all widths of elastic, but only in white. I asked the sales associate where they have the black elastic. She shrugged and said "black
elastic?" like she'd never seen such a thing.
I could not resist; I replied, "Yes, black
elastic. It's racist to only stock white elastic."
She might not have realized I was joking.
