I am doing Konmaring and I love it.
I always knew you couldn't organise clutter but always kept things just in case.
I started in October and I am in the middle of the neverending komono category.
Just redoing little girls toys and clothes (which I will keep repeating every 6 months till they are grown)
The only room I can't show visitors, is our bedroom and we are ignoring the camping pile in the hall, lol
I highly recommend it to everyone. Plus it is not minimimalist idea as pp said. If you truly love or need it, then it stays.
So I love crafts and I bet I will have several large boxs of it even when I konmari our room and that is ok.
The best part is not the tidying being easier but that I spend less time looking for things. I either know I have one and exactly where it is OR I know I don't have one. That makes all the difference.
Plus things having homes really works. We have not lost a pair of school shoes in the morning for months. Because all four pairs are on a tray in the downstairs hall. By bedtime all shoes must be on the tray. No stress in the morning !
