My goodness. I've certainly found a rich vein of interest and advice on the subject of storage. I feel as if I have the beginnings of a book on the subject! Like my friend Barbara who commented, I've been reading the comments in awe at your creativity and organisation. No matter how well my storage is planned and constructed, I suspect I'll lack the will-power and rigour to keep things tidy, but I won't have any excuses other than my own failings.
It's interesting that most of the comments have been about kitchen storage and organisation. What about my clothes...in which (if I'm honest) I'm probably more interested than I am in the kitchen? What about my yarn? What about my textile collection? Most importantly, what about the books? Are there things that you wish you'd planned for? (I've remembered such things as the vacuum cleaner, the brooms, the kitchen rubbish bin, the Christmas tree, the winter bedding). Fortunately I don't play sports so I don't need to store such things as tennis racquets or skis - that would be a nightmare in the space I have.
So, I'm still interested in other suggestions. Don't hesitate to comment again if you're so inclined.
I'm really enjoying all this interesting and valuable advice. Thank you, dear readers.
