Everything in its place, a place for everything!
This literally is my motto when it comes to organising my home. I know it might sound very old-fashioned, but if you would like to keep your house in order and be able to find whatever you want, whenever you want then you must follow this rule!
I cannot tell you how much time following this statement has saved me over the years and how efficient it makes me and my family so we have more time to enjoy life. It has taken a while to get to the point that literally everything has it's place and we have managed to create a place for everything, but having that level of organisation just makes life so simple!
No rooting around in that drawer that most people seem to have - the junk drawer and no searching the house from top to bottom to find an item which you know for a fact you have about 4 different kinds, but just can't seem to locate any of them!
So how do you go about finding a place for everything? If you're starting from scratch it probably seems like a very daunting task. My first tip is to clear the clutter! Have a major tidy up and get rid of anything that you don't need to waste your time on re-organising. Secondly, start with something small like one drawer in your kitchen or bathroom. It's too much to try to do it all at once and much more manageable to start with a very small area. That way you're more likely to get it done if you break it down into manageable chunks.
Look at each little drawer or cupboard and firstly see whether you could rearrange how the storage is used to see if you can fit more in. The storage dividers and various shaped boxes, shelving etc that you can find in IKEA are perfect to find something to divide up the space in any storage area.
Once you've organised the shelving/dividers then decide what will go back in there based on the location of the drawer/cupboard and how accessible it is. If it is very accessible then use it for something you might need to get out on a regular basis. If it's in quite an awkward place and more inaccessible then use it for things you don't need very often and won't need to be getting out in a rushed situation.
Work on each area of your home one at a time, maybe choosing one each weekend and eventually you will have worked your way round the whole house and hopefully will be so happy with how much more efficient your life has become. As long as everyone else in the house knows about your new routine of putting everything back in its place, then you'll be a lot better off in the long run and there'll be no last minute panics about where the 5 rolls of Sellotape are that you know are somewhere in the house!
