I don't usually decorate for valentines but I saw this idea here : http://organizeyourstuffnow.com/wordpressp=16934 for paper hearts and thought it was cute.
After running around all over looking for some suitable paper ( although I make cards occasionally, i am not a scrap booker so it isn't something I keep around the house normally), I found an old gift bad my Nana had sent me a gift in.
I then proceeded to butcher it :) the pretty pink cord has now gone in my sewing basket, and iron it (yes I am that crazy woman who irons old wrapping paper to use again).
I then cut the paper into strips and folded and stapled them into hearts (you can see how to in the link above).
And popped them in an empty goldfish bowl :) These bowls are fab, I have two of them from the charity shop, and can be used to display all sorts, at Christmas this one was filled lights and the glass gold baubles out of the reach of cats :)
