Some differing packing habits!!!!!!!. Some pack a few hours before they leave. I have a special travel drawer under the bed for all travel related bits and pieces kept in about 10 different shoe boxes (without lids) (yes, anal I know, but handy to stop everything getting scattered about). I. Make a list and start packing about a week before, cases on the bed in the spare room . Gradually putting stuff in, mostly in the same area if the case (yes, again, you are right, but of OCD going on there).
Last things to go in are my dive fins which just fit, and sort of keep everything in place underneath when the elasticated straps are connected
