Same thing happened to me on Friday. Went to a yardsale and they were selling rulers and mats and fabric and rick rack. Later someone was looking at my 'stuff' as I was searching the books and when I said "hey, that's mine", they wanted to know where I got it. Had to show people twice where the stuff was, but I got the good stuff !! Wish now I had bought more fabric. But I have so much I thought I shouldn't.
