Find small or leftover woodblocks or cut outs; paint them and then hang them!  They'll match perfectly, be small enough to fit in small spaces and they're storage! 

Not enough counter space?  Hang a shelf just below your mirror.  This way it won't look cluttered with another random shelf and you'll have room for more necessities. 

If you're like me, there's not enough cupboard space.  I store the "pretty" towels on top of a hanging cabinet.  No one really sees them, but they're out of the way. 

I used plain colored napkins as curtains in my bathroom.  Fold them in half at opposite corners and then hang them over the curtain rod.  You can experiment with different colors or patterns and solids.  Very cheap to do! 

If you haven't used it in 3 months, YOU DON'T NEED IT! 

For little cupboard space, store your toilet paper in a neat basket!  You can find cute small baskets at any dollar store. 

Find a clear plate and clear bowl for really cheap.  Put some sand on the plate and water in the bowl.  Set the bowl on the plate and put a floating candle in the water.  Decorate the sand with shells, stones, etc.  Perfect for a relaxing bath! 

You don't need a fancy shower curtain.  Buy 2 plain colored plastic liners, one for in the tub, one to look pretty outside.  (These can also be found at the dollar store) You can also sponge paint on these, or hang shells on a string and loop them through the shower rings.  Keeps everything simple and "clean" looking even if it's not!
