DMIL has had an accident (she is fine, just temporarily incapacitated). She is living with a relative whilst bones heal & I have been helping out but realised that the upstairs of her house is filled with 'stuff' - boxes full of random things that have never been unpacked from moving 4 years ago, washing, clothes & general 'stuff' everywhere. Before she comes home in Jan, SIL and I will need to have a real sort out as it will be a tripping hazard and also just a nightmare to live in cluttered space...but where do we start - any advice/inspiration really helpful here. thanks.
