I love 70% in my house as I have intentionally choose them. The 30% Ieft is actually for sale as I'm frugal so wouldn't just part with it and is packed away. Takes time but worth selling to me.
My peeler is a thing of beauty as was my old kitchen sink. I had a dining table for 2 years which I hated but it was cheap and then I couldn't find one I really liked. The dining table I found I love and will never part with.
Marie kondo helps with what sparks joy and I've always liked the William Morris quote. So I try to apply it to everything not just what should be decorative. Ie my microwave broke last month, it was functional but this time I choose a functional one and it is pretty. My kettles and toasters have always been pleasing to me, as have my cookers. Some household things are so pretty and I have a thing for taps, handles, light switches and light fittings. Anything can spark joy.
Taste is subjective but i try to choose everything that's pleasing to my eyes.
Never have put ornaments away from children and I used to have a lot of glass bowls and vases. When things are normal in a kids environment they don't touch them. And shelves and window sills are usually out of reach of a toddler anyway. So I've never understood the packing things away for children thing.
Clothes is the start as if it's functional like wellies or a jumper or rain jacket then choose the one that is also beautiful to you and fits your aesthetic. Your clothes should spark joy.
Also I love tights, pp upthread mentioned about who could love them? Well me, over 50 pairs and I've been collecting them since I was 13, I have some beautiful pairs, I love unusual colours and designs.
Work the Marie kondo categories before ornaments then go through them all. And if they all spark joy then keep them all.
