Paedophryne amauensis

Time it’s been driving me nuts cos the cushion comes unzipped when you sit on it: since the day I got it (months ago)
Time it took to sew up the bottom of the zip so it can’t come undone: 15 minutes (and most of that was trying to find the sewing kit :P )

Time it’s been standing in the corner of the kitchen looking derelict: 3 months.
Time it took to do something about it: 5 minutes.
