I will admit that I like to get my craft on and on.
But I don't have a lot of crafty shit just hanging out. I tend to buy what I need for a project and nothing more. So I end up with odds and ends and a whole lot of tape.
But I keep it all fairly contained within a drawer in our buffet.
If you have an entire room dedicated to crafting or just a drawer, the first rule is to contain, contain, contain. Keep all of your paints in one spot or container. Same for makers and pens and scissors and the like. Keeping everything together and grouped will make for less mess and easy retrieval when it is time to get your craft on.
