Doing craft (for nothing)

I'm in charge of the craft/handmade stall for our upcoming school fete. It's not until October but I'm getting my skates on because time has an annoying habit of skimming out of my hands. 

It's been heaps of fun scouring Pinterest for ideas. What do you think of these amazing owls? The things I'm looking to make have to be quick, cheap or free and able to be made of stuff that people have already. I'm not into spending a lot of money for a craft stall when there are so many cool upcycling things you could do.

I've been pinning ideas to my 'school fete' board here. And here are few more things I've got in mind. I'll post photos as I make them.
