Post it note keychain

Here's my first post it note keychain, dead simple and quick to make but very useful... i've seen these on so many blogs i don't know who to credit for the idea, but i've changed my sizes from all the ones i've seen as i couldn't get hold of the rectangle post its so had to use the little square ones instead..

I've used; 1 keyring, 2 felt flowers, white gems, little yellow post its and a piece of flower card 5.7cmx11.4cm
