Liberty magic wand and pumpkin!
No, seriously, it can be a painful book to read because it helps you realize some mistakes you may have been repeating (some of them expensive too). But if you do the purges and the self-analysis, it will really help.
What really irritates me is that so many clothes have poorly finished machine-sewn buttons - no knots and weak overlock machine type thread - the stitches unravel immediately. This may be really obvious to everyone else, but the next time you need to sew on buttons, make sure you buy proper button thread. It's thicker, stronger and more hardwearing (mine are 100% polyester and made by Gütermann - buy here), you can make proper knots, and if you use that, you will never need to replace that button again. I didn't know but a kind lady in a specialist shop advised me - my mother just rolled her eyes when I mentioned that she never bothered to tell me.
I hate washing silks too. I have a good washing machine and the perfect program too, but somehow getting started is a problem, plus I hate the drying and ironing part. I'm procrastinating on my silk/cotton Marni coat right now. I've actually outsourced laundry and ironing and repairs on children's clothes to our lovely Nanny and our cleaner, but feel that I should at least have the energy to wash my own woolens. You wish.
Does anyone have one of those handheld clothes steamers? Do they work? I saw a salesperson using one at COS, with miraculous results, but have forgotten to look into that.
