I had the same thing happen. A friend gave me a tee shirt to back for a wall hanging. Iput it on my sewing chair and then "forgot" where I put it so thinking it was in with my stash with the fabrics I was using I totally re folded my stash 4hours later and a neater stash I found it under my shirt on the back of the chair. I forgot I moved the chair to the other sewing table! I have 2 chairs and didnt remember which chair it was on. lol. You will find it where you least expect to find it.
