This trick is going to help me for sure.
First I will be ruthless and determine to free up my space and choose what I think is cluttering up my cupboards etc.
Then I must put all the 'clutter' on sale at our weekly carboot sale to see if I can make some pin money. I have some brand new stuff like unwanted gifts, things I have duplicates of, clothes I do not wear anymore and will never wear regardless of what I hope(!), good though used kitchen utensils and pots etc.
Then from past experience, I know there is always stuff left over that did not sell. If I can't give this away then I am going to pack it away as you suggest and see what happens.
Thanks, now to get down to doing it. Will give myself a deadline too, two weeks should be good, time enough for me to get a couple of big boxes and box tape. Makes a person think a lot about how wasteful I am too, buying more stuff when I do not need it. Oh dear.
Will keep in touch and say cheers
