When we moved house last week, I managed to inherit a huge set of drawers. four huge drawers, two smaller, and even a little armoire on the side to hang up more clothes. I love it, but the drawers are a bitch. All jammy and hard to open and close smoothly.
Now you could get someone to sand down the edges so your drawers have a little extra room, but then you'd have a lot of work to deal with, and need to find someone you're OK with seeing your scanties. This method is much quicker, and less messy.
Keep a bar of soap in your knicker drawer. Firstly it will keep your knickers smelling nice, and secondly it's great for rubbing on the corners of your drawers to make them run smooth. Give it a go and see.
For nice drawer soaps, just your normal imperial leather just won't do, My favourite pretty soap brand is
Mor, they have a huge range so you're bound to find something you like, and the packaging is so pretty you might not want to unwrap it (buy a few bars for your bathroom too). My favourite is the Black Cherry Plum.
