The theme vintage carnival was pretty easy to buy decorations for and I bought most of the items online. The signs which said things like step right up, admissions, games etc tied in with the theme well.
I bought a yellow bunting that was very pretty and balloons too. I spotted some rubber ducks in Poundland in different colours and they reminded me of hook a duck, these also worked nicely.
I also bought two table clothes, one to go in the kitchen and one to go in the conservatory. One was polka dots, like a clowns costume and the other was red and white striped.
Here are a couple of pics I took before my guests arrived...
