RE storage, I have a big house, plus plenty of stotage and still lots of clutter
The kitchen is big but we have home stuff, then greenabubs stuff which is immense, yarn, dyes, packing, containers, all ingredients for cosmetic making and most of it needs to be kept out of reach of two climbing cheeky kids! I found Ikea was great for ideas but then you dont actually have to buy the stuff from ikea , just similar.
For example these are fab! I have them in most cupboards so it doubles the space in each one
