After a great deal of measuring and deliberation I have put through an order to Ikea. There will be many flat things arriving that I will have to turn into not flat things.

It should be a good improvement for my sewing storage area, which has had a mix of random cheap storage solutions including wire cubes that don't really work that well. It's an awkard spot to get things to fit - I think it was originally a wardrobe, which the previous owner tried to turn into a bar, by putting a bench across the middle and putting an arch in the wall at the front to match an arched doorway in the room. Which means there is a really deep cupboard at the bottom which is hard to reach anything in, and the archway on top partially blocks access to shelves. I have bought the deepest drawers I can find to fit in the bottom, plus a couple of narrow trolleys on wheels that can be pulled out to get access. And some wire shelves to go on the top section that are about half the width of the bench.
