I love the cat photo! ?
Long knives go flat on the top level, small ones, blade down in the holder. We have a knife sharpener anyway.
I don’t put silver cutlery in but as it doesn’t get used more than once a year, that’s not an issue.
I put in plastic breakers etc on the top shelf and they seem to survive.
I’ve washed Lego in the DW, in one of those netting laundry bags, and recently washed the top half of a high chair in it. Istr putting unravelled knitting wool in once, to get the kinks out.
