I finally found it, but too late...
About 5 years ago, when I was visiting my Dear MIL in Coeur d'Alene, ID, she gave me a $50 gift certificate for my birthday. I could have sworn that I never used it, but still I could never find it.
Well, I just found it today, along with the birthday card and some fabric that I purchased from Joann's Fabric. And guess what? It is for Hancock Fabrics; which is now closed and out of business. Can you believe it? Nothing like being a day late and a dollar short. (let's make that $50 short - UGH!)
