No, not the quilty kind!
A real mystery. And I hope at least one of my readers knows the answer or can point me in the right direction.
While Mr. Hillside was unloading the rental van at House 2 this morning, I decided to clear my sewing off the kitchen counter to make room for unpacking and sorting.
Both fabrics had been washed before cutting, probably with Gain, and dried with Bounce (please don't lecture me about fabric softener). The iron on the ironing board showed no signs of having leaked. The fabric was near, but not ON, the Olfa cutting mat. The undercabinet lights were not on. The Keurig had not leaked. The only potential culprits I could see were a banana and an apple in a nearby bowl. I know that apples create an off-gas as they "mature." Could this be what happened? And what should I do to remove the stain?
