Speaking from experience there is nothing worse then bad packing. Last time we moved we thought "how hard can this moving thing be?!". combine that with 2 small children, parents who work 7 days a week between them and no one on the scene to babysit and actually it becomes a pretty big challange.
We bought loads of those huge re-useable bags from Tesco, Hobbycraft and other various locations and, along with lots of nappy boxes basically stuffed them to the top with books.
Then we got loads of re-usable plastic crates and filled them with anything we could find as we went along.
There was no method to the 'packing', no consideration of where it'll go the other end (I labelled a couple of boxes) in fact there was no planning went into anything.
Clothes were pretty much left on hangers and dumped in a corner to go.
lampshades, lights, and anything to big for a box well they landed in another pile.
Then hubby told me a week before we got the keys that he couldn't get the day off work to help me move house! But it was ok because he had around 5 friends and our neighbours to help (one who had a van).
So on the day of the move (with no one in sight) I set off with the boys to get the keys ..... and wait for someone to come and help move. (but anyway that's another story in itself) Lets just say moving day (which turned into moving week) was a complete and utter disaster and had me crying in many many corners. Had the packing been done properly it would have been a far smoother operation.
