A 2"x17" strip of fabric that i needed to replace a block in a quilt. I tore out four blocks, replaced two and lost the piece for the other two. I retraced every place I'd been today, cleaned several areas that needed it and nothing. Just as I was giving up for the 2nd time, I spotted a corner of it on a table. The rest had slid down near the table leg. I live with only a well behaved dog, so I can't blame anyone else.
