No, I did not misplace a turtle, although I assume he's not where I left him, either. That's just the other picture I posted from yesterday's shoot in the grass.
I have managed to misplace the calculations for the living room curtains I'm making. I can redo the calculations without too much difficulty. However, since the fabric has already been purchased (at a heavily discounted rate), if I overestimate one dimension of length, I could wind up one or more feet short of fabric on the last window. So I'd rather stick with my previous calculations and avoid the risk of under or overshoot my original plans.
I don't mind shopping at flea markets or looking for things that I don't know exist yet, but looking for something I need and can't find is probably my biggest pet peeve.
